shiny treasures japanese booster box Treasure Ex - SV4A class Pack Shiny Treasure ex (シャイニートレジャーex) set of the Pokemon TCG Scarlet & Violet: Shiny Treasure

This general ability has been seen many times before on other cards, but always with stipulations which You Came Back does not have

CCC - Surf Return 100 You may shuffle this Pokemon and all cards attached to it into your deck

Essentially, creatures are always fair game, as are artifacts and enchantments (though theres less removal for those card types at more casual tables)

That sounds like a lot of life lost, but dont worrythose cards just as easily flicker your other demons to burn the table out with Belakors other ability

(This is treated as a Fusion Summon.) You can only use this effect of "Salamandra Fusion" once per turn

Creatures aren't the only card types to utilize the Morph mechanic
