BBB has a good chance. Even better with a Mug. Drop Kick Spam, Load and Fire Cannon. A sure win.
Rathbone is a medium good counter to him, except against CC with Girdle. Rath can do damage to CC’s deck with Domination…
Gunbjorn does a good damage to him with Ice Shards. At close range it is a guessing game.
3 Ice Shards kill CC, and with Bracers Gunbjorn becomes even better against him.
OH… And VV kills CC with 2 hits, provided they both hit.
Eva can be a tough opponent against him. Force far → Fiery Passion 33 dmg. She will win with Stoneheel Totem. CC will need to do 4 Voidstreams to kill her, 3 if Tomes proc once, then it’s a tie. But if CC has Tomes and Not Girdle, then Eva has little to fear at close range with her Head Over Heels which interrupts enemy attacks and makes them attack themselves. Then it will be a guessing game at close, though…
Actually, most characters with Stoneheel Totem have a decent chance against CC. CC hates the Totem.
And finally, Bestor. If CC forces far and Bestor has the prism, suicidepyroclasm for massive deck damage. A good trade.
