Partner with Owen Grady, Raptor Trainer (When this creature enters, target player may put Owen into their hand from their library, then shuffle.) For each kind of counter on Blue, Loyal Raptor, each other Dinosaur you control enters with a counter of that kind on it.

Partner with Blue, Loyal Raptor {T}: Put your choice of a menace, trample, reach, or haste counter on target Dinosaur. Activate only as a sorcery.

Emerge {6}{U} (You may cast this spell by sacrificing a creature and paying the emerge cost reduced by that creature's mana value.) When this creature enters, if you cast it, return each non-Dinosaur creature to its owner's hand.

Destroy all tapped creatures. Until your next turn, whenever a creature becomes tapped, destroy it.

{10}{B}{G}: Monstrosity 10. This ability costs {1} less to activate for each creature with power 4 or greater your opponents control. (If this creature isn't monstrous, put ten +1/+1 counters on it and it becomes monstrous.) When this creature becomes monstrous, destroy all artifacts and creatures other than this creature.

Counter target noncreature spell. Your opponents can't cast noncreature spells this turn.

Devour 3 (As this creature enters, you may sacrifice any number of creatures. It enters with three times that many +1/+1 counters on it.) Whenever this creature attacks, it deals damage equal to its power to up to one other target creature. Excess damage is dealt to that creature's controller instead.

Henry Wu and other Human creatures you control have exploit. (When a creature with exploit enters, you may sacrifice a creature.) Whenever a creature you control exploits a non-Human creature, draw a card. If the exploited creature had power 3 or greater, create a Treasure token.

{T}, Exile a creature card from your graveyard: Discover X, where X is the mana value of the exiled card. Activate only as a sorcery. (Exile cards from the top of your library until you exile a nonland card with that mana value or less. Cast it without paying its mana cost or put it into your hand. Put the rest on the bottom in a random order.)

At the beginning of your end step, if a creature died this turn, create a tapped token that's a copy of this creature.

Imprint — {1}, {T}: Exile target creature card from a graveyard. Activate only as a sorcery. {6}: Create a token that's a copy of target creature card exiled with this artifact, except it's a 6/6 green Dinosaur creature with trample. Activate only as a sorcery.

{T}: Add one mana of any color in your commander's color identity.
