Spright Red

Endless Engine — If you control another creature with converted mana cost 2, you may cast this creature without paying its mana cost. Activate only as a sorcery.

As an additional cost to use this ability, you may sacrifice one other creature you control with converted mana cost 2. Counter target activated ability or triggered ability of opponent's creature, then destroy that creature if you sacrificed a creature.

Activate each ability of Spright Red only once per turn.
