Mulligans
This version has more control over the board, so you feel more confident against aggro decks.
Mulligans
Always keep: The Fist of Ra-Den, Hagatha's Scheme, Devoted Maniac, Far Sight and Invocation of Frost.
In some matchups worth considering: Storm Chaser, Zilliax, Faceless Corruptor, Galakrond, the Tempest, Hex or Walking Fountain.
You can replace one of Storm Chaser or Faceless Corruptor with Hoard Pillager.
