Death roulette doesn’t avoid hg and I don’t rather DR and sudden death so strong as they are based on luck and can kill your monsters.
Mine are:
Nightmare grip
Death sentence/deathmark/auto DS
Bomb curse
Last bite (not for UC)
Bloodfury
Best for UC potent sleep of Goldtail, best for pvp Bloodcrave because you can charge it with one kill and killing your bloodcraver with right timing (thanks to recoil) can be really amazing to bring in stun at right timing or set up again for next kill streak. Well those are my preferences
In UC the strongest moves are anything that applies lethal damage, so death sentence, nightmares grip, death roulette, deathmatch mode and sleep to round it off.
For pvp Team turn is by far the best move in the game, followed quote far behind by double bloodcrave (revenarchion), rebirth (hellfox), poison massacre (terrordragon) and assassinate (leo / robin)
