Mulligans
This is a fast deck that fights hard in the early game but also has massive cheap draws. Create multiple threats from bombs in the deck (blocking highlander decks) and on the board. Gain early board control as well as create early threat to the face. Fun and good against most current archetypes, though struggles with control heal priests.
At mulligan, in general you want your cheap cards. Imprisoned Gan arg is great against other agrro e.g. Demon Hunter, Warrior, Totem Shaman, even control mage. Its a great tempo swing on turn 3. Consider battle rage as important for control (mage, priest, warlock).
Strategies:
Clear boards, create boom bots and create draws using risky skipper and associated cards. Use ancharr to draw risky skipper. Frothing beserker can be played quietly the turn before risky skipper.
Initially i used a similar deck with serpent egg, but i modified it a bit and found that this worked for me on ladder.
The deck is super fun. I reached legend with it today (2020/04/21) after playing it consistently through diamond.
For some reason i can’t edit the deck. I added Grommash and took out one injured tol’vir.
