Living metal is a keyword ability found on some Vehicles. “Living metal” means “During your turn, this permanent is an artifact creature in addition to its other types.”

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 510, “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 702.19b, 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 506.4c, 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.

To convert a permanent, turn it so that its other face is up. This follows rules 701.28a–f, 712.9–10, and 712.18. Those rules apply to converting a permanent just as they apply to transforming a permanent.

Although converting a permanent uses the same physical action as turning a permanent face up or face down, they are different game actions. Abilities that trigger when a permanent is turned face down won’t trigger when that permanent converts, and so on.

If a spell or ability instructs a player to convert a permanent that isn’t represented by a transforming token or a transforming double-faced card, nothing happens.

If a spell or ability instructs a player to convert a permanent, and the face that permanent would convert into is represented by an instant or sorcery card face, or is a transforming token that was created with an instant or sorcery face, nothing happens.

If an activated or triggered ability of a permanent that isn’t a delayed triggered ability of that permanent tries to convert it, the permanent does so only if it hasn’t converted or transformed since the ability was put onto the stack. If a delayed triggered ability of a permanent tries to convert that permanent, the permanent does so only if it hasn’t converted or transformed since that delayed triggered ability was created. In both cases, if the permanent has already transformed or converted, an instruction to do either is ignored.

If a spell or ability states that a permanent can’t transform, that permanent also can’t convert.

More Than Meets the Eye represents a static ability that functions in any zone from which the spell may be cast. “More Than Meets the Eye [cost]” means “You may cast this card converted by paying [cost] rather than its mana cost.” Casting a spell using its More Than Meets the Eye ability follows the rules for paying alternative costs (see 601.2b and 601.2f–h). See rule 701.50, “Convert.”

“Bolster N” means “Choose a creature you control with the least toughness or tied for least toughness among creatures you control. Put N +1/+1 counters on that creature.”
