I use Historic Brawl to playtest REAL cards in a format which is the closest relative to EDH. Separate alchemy from historic brawl! It's hard enough reading a double sided card when you're on a timer let alone a specialize card with 5 different variations. Also Oracle of the Alpha was a mistake, especially in a format with a max deck size. The fact that only blue players can play a card which adds 9 cards to a 100 card limit deck and the fact that those cards are not available to other players in the format unless they play oracle is not a balanced feature. Conjuring as well is adding cards past the max card limit and seek is not a mechanic that can exist in real game play. None of these Alchemy mechanics are fun to play against as they break the traditional gameplay laws that exist. I understand balancing certain cards but keep alchemy in it's own category.
