[Suzogamori Ren]

Evolution Monsters are monsters placed in your Extra Deck that are played by "Evolving" a monster. Doing this places the Evolution monster on top of the evolving monster. This also counts as Special Summoning the Evolution monster. If the monster would be removed from the field, both top and bottom monsters are sent there as separate cards. De-Evolving a monster means taking the Evolution monster and returning only it to the Extra Deck. The monster it evolved from remains face-up.
