UchuulonHow it works & interactions with other cards

Scaling Power and Type Synergy

Uchuulon features a characteristic-defining ability that constantly updates its power based on the number of Crabs, Oozes, and Horrors you control. Note that its toughness is fixed at 4, but its power changes dynamically as your board state evolves. If a creature has multiple of these types, it is only counted once for Uchuulon's power calculation.

Resolving Horrific Symbiosis

The Horrific Symbiosis ability triggers at the beginning of your end step. First, you choose up to one target creature card in an opponent's graveyard. Upon resolution, if that card is successfully exiled, you create a token that is a copy of the specific Uchuulon that triggered the ability. If the targeted card is removed from the graveyard in response, the ability will fizzle and you will not get a token.

The Nature of the Token

The token created is a copy of Uchuulon as it exists on the battlefield, including its mana cost and types. Because the new token is also a Crab Ooze Horror, it immediately contributes to the power of every other Uchuulon you control. This leads to exponential growth where each new copy makes every existing one significantly stronger.

Strategic Timing

Since the trigger occurs at the end step, Uchuulon provides immediate value the turn it is played, provided an opponent has a creature in their graveyard. To maximize this, ensure you have targets available by utilizing combat or removal spells during your main phase. Once the chain starts, it becomes increasingly difficult for opponents to manage the growing swarm of Horrors.

Interaction examples

Starting the Cycle

Solemn Simulacrum

If your opponent has a Solemn Simulacrum in their graveyard during your end step, you target it with Uchuulon's ability. The Solemn Simulacrum is exiled, and you create a Copy token of Uchuulon. You now control two Uchuulons, and since both are Crab Ooze Horrors, both will now have 2 power.

Doubling the Symbiosis

Roaming Throne

With Roaming Throne on the battlefield naming 'Horror', Uchuulon's Horrific Symbiosis triggers twice at your end step. You can target two different creature cards in opponent graveyards. As each trigger resolves, you exile a card and create a Copy token of Uchuulon. By the time you reach your opponent's turn, you will have three Uchuulons and the Throne, making each Uchuulon a 4/4 creature.

Power in Numbers

Copy

Suppose you control one Uchuulon and three Copy tokens produced by its ability. Because you control four creatures with the Horror type, the original Uchuulon and all three tokens will have a power of 4. If you play another Crab or Ooze later, all four Uchuulons will immediately update to 5 power.
