Search your library for a creature card, reveal it, put it into your hand, then shuffle. Then if you control a creature with power 4 or greater, you may pay {4}. If you do, you may put a creature card from your hand onto the battlefield.

Target creature you control fights target creature you don't control. (Each deals damage equal to its power to the other.)

As an additional cost to cast this spell, pay {2} or reveal an instant or sorcery card from your hand.

Spells your opponents cast cost {2} more to cast for each card with the same name as that spell in that player's graveyard and for each nonland permanent on the battlefield with the same name as that spell.

Vigilance
Whenever another creature you control enters, scry 1.
{T}: Reveal the top card of your library. If it's a creature card, put it into your hand. Otherwise, you may put it into your graveyard.

Haste

{T}: Add {C}.
Whenever you tap Primal Channeler for mana, the next creature spell you cast this turn can be cast as though it had flash.

({T}: Add {B}, {R}, or {G}.)
Primal Dominion enters tapped.

Reach
You may cast a copy of Primal Echo from your graveyard by exiling it and paying {2} in addition to its other costs. (The copy enters as a token.)

Reveal the top seven cards of your library. You may put a creature card from among them onto the battlefield. Put the rest into your graveyard. Then flip a coin. If you win the flip, return Primal Evocation to its owner's hand.

Enchant land
Enchanted land has “{T}: Add {G}{G}.”

Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)
Whenever Primal Ruffian attacks, if it has a +1/+1 counter on it, other creatures you control get +1/+1 until end of turn. (If it had no counters on it when it attacked, this ability does not trigger.)

Distribute a vigilance, trample, first strike, and lifelink counter among up to four target creatures you control, then distribute four +1/+1 counters among those creatures.
