Replicate

Replicate is a keyword ability attributed to the Izzet in the Guildpact set of the Ravnica block. It works by putting copies of a given instant or sorcery onto the stack for each time you pay the Replicate cost. So far, each card printed with Replicate has had a Replicate cost equal to its mana cost.

Rulings

• Copies created with replicate will have replicate abilities themselves. However, since those copies aren't played, their replicate costs can't be paid and their replicate abilities won't trigger.

• Each copy is separate. If one of them is countered (including the actual spell card), the rest remain on the stack.

• If the replicate trigger is countered (by the Scourge spell Stifle, for example), no replicate copies will be created. The original spell will be unaffected.
