Searing Spear deals 3 damage to any target.

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

Create a 3/3 green Centaur creature token.

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

Choose one — • Counter target noncreature spell unless its controller pays 2. • Izzet Charm deals 2 damage to target creature. • Draw two cards, then discard two cards.

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.)

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.

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.)
