General Mulligans
Disciple / Pools / Traveler only when going second or already having the other cheap options. If u have a nice curve, might even leave Flutter guardian / Oaken summons. Mistah Vistah can be kept if you have Trail Mix.
Spam spells to grow you hero power. Discount Meadowstrider with traveler to play him early and then pull him back from your deck via oaken summons. Get more oaken summons from HornOP or Tide Pools, MVistah, ocassionally get shalladrassil. Ideally save Bob to multiply Striders when you run out of the few minions that this deck gets, freeze the board when in pinch or do an UNO reverse on enemy Ceasless Expanse. Use grove shaper to get more oaken summons / horns / symbiosis etc.
