Main Combos:
Psylocke on 2 > Wong on 3 (in a free space) > Wave on 4 (in a place different from Psylocke) > Onslaught on 5 (same place as Wong) > Mystique and Hazmat (if your opp. has more cards than you) / Gambit / Ironheart on 6
Wong on 4 > Magik on 5 > Onslaught on 6 > Mystique and Hazmat (same as before) / Gambit / Ironheart on 7
For this scenario, Warlock and Colossus must to be played together on turns 2 and 3 for Warlock's skill trigger (with some luck) and Magik is played away from them
Secondary Combos:
Psylocke on 2 > Negative on 3 > Same as before (Mystique after Onslaught, Wong and Hazmat/Gambit/Ironheart)
Wong > Mystique > Gambit/Hazmat - This one is for brick hands
If Negative procs on Onslaught:
Psylocke on 2 > Negative on 3 > Wave on 4 > Onslaught on 5 (4 cost) > Mystique (0 cost), Wong (2 cost) and Hazmat/Gambit/Ironheart
If you don't have luck:
Gambit and Hazmat might surprise your opp. the first can removes one threat from the board and (against spamming) Hazmat works pretty nice.
Warlock is incredible if you know how to play it, an early ironheart/hazmat might give you at least one extra draw
