• Put two +1/+1
countersTo counter a spell or ability is to cancel it: remove it from the stack without resolving it. A counter on an object or player is instead a marker that changes characteristics or interacts with rules or abilities; for example, a +1/+1 counter modifies a creature’s power and toughness. (CR 701.6; 122.1) on this creature.
• Put target exiled card with
warpWarp represents two static abilities that function while the card with warp is on the stack, one of which may create a delayed triggered ability. “Warp [cost]” means “You may cast this card from your hand by paying [cost] rather than its mana cost” and “If this spell’s warp cost was paid, exile the permanent this spell becomes at the beginning of the next end step. Its owner may cast this card after the current turn has ended for as long as it remains exiled.” Casting a spell for its warp cost follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.
Some effects refer to “warped” cards in exile. A warped card in exile is one that was exiled by the delayed triggered ability created by a warp ability.
Some effects refer to whether “a spell was warped this turn.” This means that a spell was cast for its warp cost this turn. (CR 702.185) on the bottom of its owner's library.
