Wow the ones saying this card is bad have absolutely no idea what they are talking about.
“get OTK'd next turn because you left a 200 attack monster in attack mode.”
Seriously, can someone be that... dumb? you are supposed to summon the little guy, wait if it doesn't get canadia'd floodgated (He isn't likely to trigger that trap anyway) if you opponent lets you summon it, then you activate it's effect. Summon cosmo brain discarding a dragon, then tribute Sasuke Samurai and summon Blue Eyes. You'll have 6100 ATK DMG on the field.
To think you actually believe you leave this guy on the field... is just disappointing. I kinda lose all my faith in humanity as an evolving race.
