Since the requirement for the fusion materials can be pretty open, you can use 2 of the same high level monsters to fuse into Pair Cycroid to deal direct damage, and the use De-Fusion to bring out your high level monsters to the field.
I've been trying to get this card to try to unlock zane for around 1000 yellow keys worth of dueling with syrus lv40. If anyone got Pair Cycroid, around how much yellow keys worth of dueling did it take for you to get it(with syrus lv30 or lv40)?
This card is impossible to get, I understand it is super rare but I have farmed him fo4 hours and gotten nearly every other SR from him. I just wan5 Zane and this game makes it almost impossible if you missed the event
