Cycle your deck through cheap cardraw, thinning with meatwagon, meanwhile control the board with the fitting package, good tools with efficent removals , and plenty of health restoration to stand against any kind of enemy.

The combo is to pull of doomguard (your only demon) with skull of manari and because its the start of your turn you have the full mana pool to combo. After attack with Dg. Cube it , kill it with pactt attack with 2 dg, iff opponent remove dg-s you have another try, finally if your opponent survives this much damage you can finally Dk with 6 doomguards (best case scenario)

Worst case: your weapon get removed- you can run rummaging cobold , but i dont think there will be that much weapon removal,  even if they do remove it,can try to pull the combo of with meatwagon-summoning portal-doomguard-cube-pact, cause you have plenty of cards in your hand, but may discard important pieces so be aware.

Good luck, have fun.
