First strike (This creature deals combat damage before creatures without first strike.)
Whenever Ogre Battlecaster attacks, you may cast target instant or sorcery card from your graveyard by paying
in addition to its other costs. If that spell would be put into a graveyard, exile it instead. When you cast that spell, Ogre Battlecaster gets +X/+0 until end of turn, where X is that spell's mana value.
