Cryocore

 is an archetype of WATER Pyro monsters created by The Nepfessor and used by Yuriko Kobayashi in his continuity. The archetype's Main Deck monsters usually have low ATK, which can be used for attacking directly, while it is supported by the "Frostflame" series of Spell/Trap Cards. They are focused on a mix of Royal and Enchant Summoning of their "Deity" ace monsters, by exploiting said "Frostflame" cards.
