Surveil 2, then choose an instant or sorcery card in your graveyard. You may cast it this turn. If that spell would be put into your graveyard, exile it instead. (To surveil 2, look at the top two cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.)

During your turn, creatures you control get +1/+0 and have trample.

Whenever you surveil for the first time each turn, this creature deals 1 damage to each opponent and you gain 1 life.

Destroy all creatures with toughness 4 or greater.

Flying Mentor (Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.) When this creature dies, put a +1/+1 counter on each white creature you control.
