Until end of turn, creatures you control get +2/+2 and gain menace and "Whenever this creature attacks, you gain 1 life." (A creature with menace can't be blocked except by two or more creatures.)

Reach Increment (Whenever you cast a spell, if the amount of mana you spent is greater than this creature's power or toughness, put a +1/+1 counter on this creature.)

When Ennis enters, exile up to one other target creature you control. Return that card to the battlefield under its owner's control at the beginning of the next end step. At the beginning of your end step, if one or more cards were put into exile this turn, put a +1/+1 counter on Ennis.

This spell costs 2 less to cast if one or more cards left your graveyard this turn. Wilt in the Heat deals 5 damage to target creature. If that creature would die this turn, exile it instead.

This land enters tapped. T: Add W or B. 2WB, T: Surveil 1. (Look at the top card of your library. You may put it into your graveyard.)
