Primeval Spawn rulings
As long as mana was paid for any cost to cast Primeval Spawn, it enters the battlefield as it resolves. It will not be exiled as it tries to enter the battlefield, even if its cost was reduced or a cost other than its normal mana cost was paid.
If Primeval Spawn is exiled by its first ability as it tries to enter the battlefield, it goes directly to the exile zone without entering the battlefield first. Since it never enters or leaves the battlefield, its last ability won’t trigger.
If an effect causes a card to enter the battlefield as a copy of Primeval Spawn and that permanent wasn’t cast or no mana was spent to cast it, that card will be exiled instead of entering the battlefield.
Conversely, if an effect would cause Primeval Spawn to enter the battlefield as a copy of another permanent, it will enter the battlefield as a copy of that permanent whether or not it was cast or mana was spent to cast it.
If a creature token that is a copy of Primeval Spawn would be put onto the battlefield, it’s put into exile instead and then ceases to exist. Creature tokens are never cast, even if the spell that created them was.
If an effect from a static ability would remove all abilities from Primeval Spawn if it were on the battlefield (such as that of Humility), then its first ability won’t cause it to be exiled. It will enter the battlefield as normal.
Primeval Spawn’s last ability checks the mana values and types of the spells on the stack, not the mana values and types of the cards in exile. Notably, this means that you may cast the back face of a modal double-faced card or either face of a split card as long as the spells you are casting together have a total mana value of 10 or less.
The spells are cast one after the other during the resolution of Primeval Spawn’s last ability. The one you cast last will be the first one to resolve.
If you cast a spell without paying its mana cost, you can’t choose to cast it for any alternative costs. You can, however, pay any additional costs. If the spell has any mandatory additional costs, you must pay those.
If the spell has
in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.
Primeval Spawn keyword rules
Lifelink Rule 702.15
Lifelink is a static ability.
Damage dealt by a source with lifelink causes that source’s controller, or its owner if it has no controller, to gain that much life (in addition to any other results that damage causes). See rule .
If an object changes zones before an effect causes it to deal damage, its last known information is used to determine whether it had lifelink.
The lifelink rules function no matter what zone an object with lifelink deals damage from.
If multiple sources with lifelink deal damage at the same time, they cause separate life gain events (see rules –10).
Multiple instances of lifelink on the same object are redundant.
Vigilance Rule 702.20
Vigilance is a static ability that modifies the rules for the declare attackers step.
Attacking doesn’t cause creatures with vigilance to tap. (See rule , “Declare Attackers Step.”)
Multiple instances of vigilance on the same creature are redundant.
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.
