Its all konami fault, she should make the players use the mobs of current faction, dragon team can only use dragon mobs, mage team only use mage mobs, and spell and traps is up to player to choose. Too bad konami lets everyone use anything, this event could be really fun though
That would make it worst, because spellcaster team will always be winning playing full spellbooks decks while dragon team just dragon decks like blue eyes lol.
Dragon users can use Horus to try to combat Spellbook.
Although, the biggest issue here is not type of deck, but the fact that they didn't filter player ranking. You can be a Bronze facing a Legend, or a Rookie facing a KOG. That's really stupid.
