My response to this ambipom shit
If you know me, you know I hate ambipom, and think it's generally stupid, so here's some calcs to back up Moose since his calc is failing to work with beat up
252 Atk Life Orb Ambipom Low Kick (120 BP) vs. 252 HP / 252+ Def Registeel: 153-182 (42.03 - 50%) -- guaranteed 3HKO
252 Atk Life Orb Ambipom Beat Up vs. 248 HP / 252+ Def Cofagrigus: 143-169 (44.82 - 52.97%) -- 0.39% chance to 2HKO (assuming 108 damage from calculations) (assuming you're willing to keep your entire team perfectly healthy just to use 1 move, which generally means, you'll be making shit plays to keep 1 move at a base power which barely manages to 2HKO one things checks, come on people, the amount of support this move needs to be consistently USABLE is ridiculous)

And those calcs bar the Cofagrigus calc are all with 135 BP Beat Up (cofag calc because of mummy which in that case it's 108 BP if we're assuming mummy works that way) and generally perfect conditions for ambipom, and oh look, it has a assload of COUNTERS, not even just checks, but an assload of non niche counters, no pokemon in the UU tier can boast this much of full on non niche counters, which honestly makes using ambipom very hard seeing as, well, there's so much that can stop it! (druddi and quag are NOT niche purely for beating ambi people, they're good pokes if you damn gave them a try) not to mention the amount of CHECKS it has, don't even get me started on that.
Overall ambipom requires too much support (in the case of beat up) and is generally too easily stopped for it to imo be considered a A rank tier threat.
but that's just some food for thought for you guys that are boasting that ambipom has 3 checks, and 3 counters, which is FAR from close to true, and for the people that are saying that ambipom has an assload of pokemon that can stop it.
