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.

Search your library for a creature card, reveal it, put it into your hand or graveyard, then shuffle.

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.

When this land enters, choose a land card name. Activated abilities of sources with the chosen name can't be activated unless they're mana abilities. Lands with the chosen name have "T: Add C." T: Add C.

Look at the top three cards of your library. Put one of them into your hand and the rest on the bottom of your library in any order. If there is an instant card and a sorcery card in your graveyard, instead put two of them into your hand and the rest on the bottom of your library in any order.

Ward 2 (Whenever this creature becomes the target of a spell or ability an opponent controls, counter it unless that player pays 2.) Repartee — Whenever you cast an instant or sorcery spell that targets a creature, this creature gets +1/+0 and gains lifelink until end of turn.
