That would make deckbuilding pointless as you could draw into whatever you want and run like a 100 cards and have your deck be super consistent. Though i suppose that would explain why Yamigedo didnt draw badly even tho his final boss deck was complete trash even if you ignore the fact it contains 100 cards.
