This is definitely worth playtesting in different creature based decks
EDIT: Heres the comprehensive list pulled from Bulbapedia for everyones convenience: Pikachu Generations Magikarp Generations Tangela Generations Clefairy Generations Meowth Generations Geodude Generations Ponyta Generations Slowpoke Generations Charmander Evolutions Electabuzz Evolutions Cosmog Sun & Moon Alolan Vulpix Guardians Rising Stufful Burning Shadows Jangmo-o Crimson Invasion Piplup Ultra Prism Fennekin Forbidden Light Looks like there are sixteen total cards with the TRU logo
Hexproof prevents targeting, making removing this beast a difficult task for any opponent, and Annihilator 2 forces other players to sacrifice two of their permanents whenever the Breaker of Creation sets its sights on them and attacks
But it's better as it also generates a token if you attack with a Goblin, with itself also being a Goblin for this trigger
In particular, Tyranitar, Umbreon, and Espeon Rare Holos fetch a very high price
Green also has decent tools to actually defeat battles, although we havent yet had a prominent mono-green aggro deck this season
