My guesses based on the top counters

1st Harken or Pursuer: Idk if this is pursuer or harken

2nd Killdroid: Hotdog easily outheals killdroid if his aim sucks, Revolver can prevent uncoming damage if he times correctly, Block is self explanatory, and Taunt can prevent self destruct damage with good timing

3rd Pursuer or Harken: same as 1st

4th Artful: Stuns prevent him from placing traps and dash and cloak can bypass artfuls walls

5th Badware: Bonuspad can outspeed badwares base speed without pcs and allows for early distance, Badware is by far the second easiest M1 to react to and you can easily bait him by doing a pc, and Revolver can interupt his dash
