Dark Magician Cosmo Brain Deck is added to Deck Section
Cannot be Normal Summoned/Set. Must first be Special Summoned by sending 1 non-Effect Monster from your hand or face-up field to the GY. This card gains ATK equal to the Level of the monster sent to the GY this way x 200. You can Tribute 1 Effect Monster; Special Summon 1 Normal Monster from your hand or Deck. You can only use this effect of "Cosmo Brain" once per turn.
Why the hell is this broken piece of crap not banned. Special summon 3000 attack monster from the goddamn deck and guaranteed in starting hand. It’s bizarre. To make things worse, it works even with a normal monster on the field, so when they draw their 2nd and 3rd Cosmo Brains, they fill the board with 3100 monsters instantly. It’s bizarre.
