Can be used each time your Life Points decrease by 1000. During this turn, if a monster whose original name is "Cycroid" or "Pair Cycroid" attacked this turn, that monster will be banished until the beginning of your next turn.
One good Roid Deck I've found is a Cyber Dragon Roid Fusion Deck.
You can potentially replace Swamp Creature with another Cyber Dragon Zweil.
flash fusion did work with this skill, i mean 3 times attack and the fusion gets banished 1st (means it did not get destroyed)
remember this skill only active when you get -1000 lp (cosmic cyclone or even dicephoon)
still trying geargias & karakuris
