Rocksteady, Mutant Marauder rulings

2026-01-27
Both commanders start in the command zone, and the remaining 98 cards your deck are shuffled to become your library.
2026-01-27
Note that the target player searches their library (which may be affected by effects such as that of Stranglehold) and that the card they find is revealed, even though these words aren't included in the ability's reminder text.
2026-01-27
An effect that checks whether you control your commander is satisfied if you control one or both of your two commanders.
2026-01-27
The triggered ability of the "partner with" keyword still triggers in a Commander game. If your other commander has somehow ended up in your library, you can find it. You can also target another player, whether or not they have that card in their library.
2026-01-27
"Partner with [name]" represents two abilities. The first is a triggered ability: "When this permanent enters, target player may search their library for a card named [name], reveal it, put it into their hand, then shuffle."
2026-01-27
If your Commander deck has two commanders, you can only include cards whose own color identities are also found in your commanders' combined color identities. If Bebop, Skull and Crossbones and Rocksteady, Mutant Marauder are your commanders, your deck may contain cards with black and/or green in their color identities, but not white, blue, or red.
2026-01-27
Once the game begins, your two commanders are tracked separately. If you cast one, you won't have to pay an additional the first time you cast the other. A player loses the game after having been dealt 21 damage from one of them, not from both of them combined. Command Beacon's effect puts one into your hand from the command zone, not both.
2026-01-27
The second ability represented by the "partner with [name]" keyword modifies the rules for deck construction in the Commander variant and has no function outside of that variant. If a legendary creature card with "partner with [name]" is designated as your commander, the named legendary creature card can also be designated as your commander.
2026-01-27
To have two commanders, both must have the partner ability or corresponding "partner with" abilities as the game begins. A creature with a "partner with" ability can't partner with any creature other than its designated partner. Losing a partner ability during the game doesn't cause either to cease to be your commander.

Rocksteady, Mutant Marauder keyword rules

Partner Rule 702.124

Partner abilities are keyword abilities that modify the rules for deck construction in the Commander variant (see rule ), and they function before the game begins. Each partner ability allows you to designate two legendary cards as your commander rather than one. Each partner ability has its own requirements for those two commanders. The partner abilities are: partner, partner with [name], friends forever, choose a Background, and Doctor’s companion.

Your deck must contain exactly 100 cards, including its two commanders. Both commanders begin the game in the command zone.

A rule or effect that refers to your commander’s color identity refers to the combined color identities of your two commanders. See rule .

Except for determining the color identity of your commander, the two commanders function independently. When casting a commander with partner, ignore how many times your other commander has been cast (see rule ). When determining whether a player has been dealt 21 or more combat damage by the same commander, consider damage from each of your two commanders separately (see rule ).

If an effect refers to your commander while you have two commanders, it refers to either one. If an effect causes you to perform an action on your commander and it could affect both, you choose which it refers to at the time the effect is applied.

Different partner abilities are distinct from one another and cannot be combined. For example, you cannot designate two cards as your commander if one of them has “partner” and the other has “partner with [name].”

If a legendary card has more than one partner ability, you may choose which one to use when designating your commander, but you can’t use both. Notably, no partner ability or combination of partner abilities can ever let a player have more than two commanders.

“Partner” means “You may designate two legendary creature cards as your commander rather than one if each of them has partner.”

“Partner with [name]” represents two abilities. It means “You may designate two legendary creature cards as your commander rather than one if each has a ‘partner with [name]’ ability with the other’s name” and “When this permanent enters, target player may search their library for a card named [name], reveal it, put it into their hand, then shuffle.”

“Friends forever” means “You may designate two legendary creature cards as your commander rather than one if each of them has friends forever.”

“Choose a Background” means “You may designate two cards as your commander rather than one if one of them is this card and the other is a legendary Background enchantment card.” You can’t designate two cards as your commander if one has a “choose a Background” ability and the other is not a legendary Background enchantment card, and legendary Background enchantment cards can’t be your commander unless you have also designated a commander with “choose a Background.”

“Doctor’s companion” means “You may designate two legendary creature cards as your commander rather than one if one of them is this card and the other is a legendary Time Lord Doctor creature card that has no other creature types.”

If an effect refers to a partner ability by name, it means only that partner ability and not any others. If an effect refers to the partner ability or cards with partner and doesn’t mention a specific variant of the partner ability by name, it is referring only to partner, partner with [name], or cards with either of those abilities, and does not refer to any other partner variant.

Trample Rule 702.19

Trample is a static ability that modifies the rules for assigning an attacking creature’s combat damage. The ability has no effect when a creature with trample is blocking or is dealing noncombat damage. (See rule , “Combat Damage Step.”)

The controller of an attacking creature with trample first assigns damage to the creature(s) blocking it. Once all those blocking creatures are assigned lethal damage, any excess damage is assigned as its controller chooses among those blocking creatures and the player, planeswalker, or battle the creature is attacking. When checking for assigned lethal damage, take into account damage already marked on the creature and damage from other creatures that’s being assigned during the same combat damage step, but not any abilities or effects that might change the amount of damage that’s actually dealt. The attacking creature’s controller need not assign lethal damage to all those blocking creatures but in that case can’t assign any damage to the player or planeswalker it’s attacking.

Trample over planeswalkers is a variant of trample that modifies the rules for assigning combat damage to planeswalkers. The controller of a creature with trample over planeswalkers assigns that creature’s combat damage as described in rule , with one exception. If that creature is attacking a planeswalker, after lethal damage is assigned to all blocking creatures and damage at least equal to the loyalty of the planeswalker the creature is attacking is assigned to that planeswalker, further excess damage may be assigned as the attacking creature’s controller chooses among those blocking creatures, that planeswalker, and that planeswalker’s controller. When checking for assigned damage equal to a planeswalker’s loyalty, take into account damage from other creatures that’s being assigned during the same combat damage step, but not any abilities or effects that might change the amount of damage that’s actually dealt.

If an attacking creature with trample or trample over planeswalkers is blocked, but there are no creatures blocking it when damage is assigned, its damage is assigned to the defending player and/or planeswalker as though all blocking creatures have been assigned lethal damage.

If a creature with trample over planeswalkers is attacking a planeswalker and that planeswalker is removed from combat, the creature’s damage may be assigned to the defending player once all blocking creatures have been dealt lethal damage or, if there are no blocking creatures when damage is assigned, all its damage is assigned to the defending player. This is an exception to rule , and it does not cause the creature to be attacking that player.

If a creature without trample over planeswalkers is attacking a planeswalker, none of its combat damage can be assigned to the defending player, even if that planeswalker has been removed from combat or the damage the attacking creature could assign is greater than the planeswalker’s loyalty.

Multiple instances of trample on the same creature are redundant. Multiple instances of trample over planeswalkers on the same creature are redundant.
