Sudden Substitution #11

Aug 23, 2019

A mana ability is an ability that produces mana, not an ability that costs mana.

If a permanent spell is exchanged this way, its new controller will control the permanent it becomes.

Aug 23, 2019

If the exchange doesn't happen but the spell is still a legal target, its controller may choose new targets for it.

Aug 23, 2019

If the target spell or the target creature is an illegal target as Sudden Substitution resolves, the exchange won't happen. If both targets are legal but are both controlled by the same player, the exchange won't happen.

Aug 23, 2019

In a multiplayer game, if the controller of one of the objects leaves the game after Sudden Substitution resolves, the effect that gave them control of the spell or permanent expires. If the spell is still on the stack, the player who gains control of it this way can't choose new targets for it.

The exchange lasts indefinitely. It doesn't expire for the spell if the creature changes zones or leaves the game, or vice versa.

Aug 23, 2019

The noncreature spell is still on the stack after exchanging control, and the creature is still on the battlefield.

After a spell with split second resolves (or otherwise leaves the stack), players may again cast spells and activate abilities before the next object on the stack resolves.

Mar 19, 2021

Casting a spell with split second won't affect spells and abilities that are already on the stack.

Mar 19, 2021

If the resolution of a triggered ability involves casting a spell, that spell can't be cast if a spell with split second is on the stack.

Mar 19, 2021

Players may turn face-down creatures face up while a spell with split second is on the stack.

Mar 19, 2021

Players still get priority while a card with split second is on the stack; their options are just limited to mana abilities and certain special actions.

Mar 19, 2021

Split second doesn't stop triggered abilities from triggering, such as that of Chalice of the Void. If one does, its controller puts it on the stack and chooses targets for it, if any. Those abilities will resolve as normal.
