Metagame: What Mega do you think are underrated in the current meta
In the current Metagame what Megas do you think are underrated and could with the right strategy when found perform well.
Personally I tested Mega-Venusaur and Mega-Ampharos.
M-Venusaur runs into a lot of problem atm, the abundant of flying and fire types makes it quite hard. Fire types are less of problem thanks to thick fat but, flying types are a real problem. The positive its quite good into all fairy types atm with the exception of M-Gardevoir. My personal set I run is Earth Power, Gigadrain, Sludge bomb and protect. The current team I run with it it Slowking with scald, protect, psychic and trickroom if the enemy team is faster. Talonflame Acrobatics, tailwind, flareblitz and will-o-wisp for the fast mode if enemy team is slower(Galewing Acrobatics can be a live safer since it get priority even in trickroom). Kinggambit for Mega-Gengar and Psychic types, knocktow cleave, protect, ironhead and suckerpunch. Last one is Dragapult as fast attacker, honestly if its movepool would just be a little bit better it would rock, but I would argue its the most replaceable with an other Pokemon on the team.
M-Ampharos honestly suffers from its poor ability Moldbreaker is just not good enough on it. That it got both Parabolic charge and rising voltage is it only saving grace, should we get another format that about this one in power level and with terrain setter I can see it maybe getting some niche play. Moldbreaker sadly breaks any synergy it could have with Lightning Rod or voltabsorb pokemon. It needs to be played in trickroom its just too slow outside of it. Honestly the one thing it got going for it currently it hits all flying types and rain team quite hard and is somewhat neutral to good into Charizard-Y teams. Problem is Sandteams and Garchomp being used by so many people. It can use magnetic flux before mega if possible to make it more tanky if you run it with plus ability. With a slightly bigger movepool and/or better ability it could have been quite good in trickroom.
Pokemon I have not tested but think could be good, are M-Grenninja and maybe M-Chandelure should screens get more popular.
