Mulligans
Aggro Mulligans
Always keep volcanic potion against Paladin, Rogue, and Shaman. It's worth it to keep it against Warlock as it's obviously good against zoo, but it's not bad against cubelock either, due to cards like kolbold librarian and mistress of mixtures. You might want it against druid too in case it's token, better safe than sorry.
Control Mulligans
Discover cards are pretty safe to keep against most control matchups, but it's smart not to play them until you're absolutely sure what you're up against.Based off of Brian Kibler’s elemental mage, but with archmage antonitas and baron geddon substituted for two volcanic potions for aggro. This deck is intended for climbing ranks. It’s very good against cubelock and big spell priest. The volcanic potions are to save you from aggro paladin, zoo, token druid, and tempo rogue.
