Trickbind

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.

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

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.

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

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.

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.

Activated abilities contain a colon. They’re generally written “[Cost]: [Effect].” Some keywords are activated abilities and will have colons in their reminder text.

If Trickbind counters an activated ability of a permanent, no activated abilities of that permanent can be activated for the remainder of the turn. This includes activated abilities other than the one that was countered, as well as any mana abilities that permanent may have. Other abilities of that permanent, including triggered abilities and static abilities, are unaffected.

Trickbind can be used to counter the echo triggered ability. If so, the echo ability won’t trigger again so the echo cost is never paid.

Trickbind can be used to counter the flanking triggered ability.

Trickbind can be used to counter the madness triggered ability. The affected card will remain exiled.

Trickbind can be used to counter the storm triggered ability. Doing so prevents the copies from being created, but doesn’t counter the original storm spell.

Trickbind can be used to counter the suspend “remove a counter” ability. If so, the counter won’t get removed, but the ability will trigger again as normal later on. Trickbind can also be used to counter the suspend “play this card” ability. If so, the card stays exiled (the ability won’t trigger again). Using suspend to exile a card in your hand is neither an activated nor a triggered ability, so it can’t be countered this way.

Trickbind can’t counter or prevent paying the morph cost to turn a face-down creature face up, since that action doesn’t use the stack.
