Mulligan for 1/2 mana cards, keep devolve/hex against priest/druid, keep Maelstrom portal vs warrior, rogue, druid, shaman.
Don't hesitate to play Corsair on turn 1 even against pirate warrior, the board presence is much more important than the weapon removal. Don't get too greedy with evolve, you can win without the Doppelgangster combo (except against control priest/mage, that's the worst matchup for the deck I think)
