Ursaring

Depends on your plan with it. I honestly have an Ursaring with every different combination. For now, people will say use a C/CC in a Ttar fight.

Counter is more versatile in my opinion.

I'm getting the most options possible to beat Tyranitar with the fewest number of players (I think it can be done with 3). Thinking for Ursaring to ever be in that conversation: C/CC best. C/PR and MC/CC next best

Counter is super-effective against Dark, Rock, Ice, Steel, Normal
Metal Claw is only super-effective against Fairy, Rock and Ice
So, Counter is more relevant in current meta and is more uselful.
