Useless...stage 60 and battling an AI with that ritual mosnter (3000 ATK or something) and it doesn't state anywhere that it nullifies card effects, so why did it destroy my celtic guardian? I've seen this a few times a swell, more than 1900 ATK monster beats my celtic even tho no card effects are involved. So, useless!
Idk why people say it's useless, just equip it with something that gets his attack high and it's invincible. I use a deck full of warrior equip spell cards and I win 90% of the time, and use Joey for the 200+ for warriors
