Basically skip early game to reduce Gnolls to 0, then Gnoll + Sonya is infinite APM board clear. Backstab, Extortion, Bone Spike help us to reduce Gnoll’s hp. Use this combo to juice up Graveyard, Draka, Denathrius. Kael helps us to cast Den, also you can like use Kael to completely cheat out the game:
Kael, Gnoll, Sonya for 0, then bunch of Gnolls, till there’s few hp left, then Draka for 0, Gnoll attack, Gnoll, Den for 0.
And don’t forget Prep/Bone Spike interaction to reduce our Kael for an even earlier broken shenanigans.
