Call of the Conclave

You have no maximum hand size. T: Add C.

Reveal the top five cards of your library. You may put a creature or land card from among them into your hand. Put the rest into your graveyard.

Unleash (You may have this creature enter with a +1/+1 counter on it. It can't block as long as it has a +1/+1 counter on it.)

When this creature enters, target opponent reveals their hand. You choose an instant or sorcery card from it and exile that card.

Search your library for a Plains, Island, Swamp, or Mountain card, put it onto the battlefield tapped, then shuffle.

Choose one — • Counter target sorcery spell. • Destroy target creature with power 2 or less. • Look at the top three cards of target player's library. Put one back and the rest into that player's graveyard.

Flying Sacrifice this creature: Counter target instant or sorcery spell unless its controller pays 1.

Evolve (Whenever a creature you control enters, if that creature has greater power or toughness than this creature, put a +1/+1 counter on this creature.) Remove two +1/+1 counters from this creature: Regenerate it. (The next time this creature would be destroyed this turn, instead tap it, remove it from combat, and heal all damage on it.)
