Verrak, Warped Sengir

Verrak’s triggered ability creates another instance of that activated ability on the stack. It doesn’t cause any object to gain an ability.

If the activated ability’s cost contains a choice, such as a creature to sacrifice or a number of counters to remove, the copy uses that same information. You can’t pay the cost again, even if you want to.

In some cases involving linked abilities, an ability requires information about “the exiled card.” When this happens, the ability gets multiple answers. If these answers are being used to determine the value of a variable, the sum is used. If an ability attempts to create a token that is a copy of “the exiled card,” it creates a token for each card exiled this way that is a copy of that card.

If the ability is modal (that is, if it says, “Choose one —” or similar), the mode is copied and can’t be changed.

If the ability divides damage or distributes counters among a number of targets, the division and number of targets can’t be changed. If you choose new targets, you must choose the same number of targets.

Any choices made when the ability resolves won’t have been made yet when it’s copied. Any such choices will be made separately when the copy resolves.
