Mutate (If you cast this spell for its mutate cost, put it over or under target non-Human creature you own. They mutate into the creature on top plus all abilities from under it.)

Whenever this creature mutates, tap up to X target creatures, where X is the number of times this creature has mutated. Those creatures don't untap during their controller's next untap step.

When Frenzied Gorespawn enters, for each opponent, goad target creature that player controls. (Until your next turn, those creatures attack each combat if able and attack a player other than you if able.)

Whenever one or more creatures attack one of your opponents, those creatures gain menace until end of turn.

When Glistening Goremonger dies, each opponent sacrifices an artifact or creature of their choice.

Sacrifice Gore Vassal: Put a -1/-1 counter on target creature. Then if that creature's toughness is 1 or greater, regenerate it.

Bloodthirst 2 (If an opponent was dealt damage this turn, this creature enters with two +1/+1 counters on it.)

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 Goretusk Firebeast enters, it deals 4 damage to target player or planeswalker.

Each creature you control with a mana ability gets +2/+2.

Whenever a creature you control with a mana ability attacks, untap it.

Whenever you cast a spell, if at least seven mana was spent to cast it, untap target creature. It gets +7/+7 and gains trample until end of turn.

Menace

Whenever another creature you control with power 2 or less enters, surveil 1. (Look at the top card of your library. You may put it into your graveyard.)
