Elemental Shaman (Witchwood)

Mulligan for Hagatha, then everytime you play a minion you get a spell => after bogshaper is down every time you cast a spell you draw a minion. Which will get you nearer to Kalimos/Grumble Combo.

Synergies: Acolyte + Volcano (3 card draws, and board clear most of the time) plus put an arcane tyrant uf you have it.

Reduce the cost of Elementals if you have a lot of elementals in your hand. If possible keep one fireplume harbinger to reduce Grumble Worldshaker and Kalimos Primallord, so its easier to play a good Combo.
