Alchemy could be a good format, if it didn't introduce card generation, "perpetualness", and increase randomness. Those are three of the major reasons that I left Hearthstone, and now WOTC are introducing what's bad about that game. If Alchemy focused on re-balancing the meta, and increasing deck diversity instead of value generation then it would be a welcome change. Until then WOTC are pushing a bad format (alchemy), and ruining the MTG Arena experience.
