Competitive Team HelpHaving trouble with your competitive Pokémon team? Be sure to check here if you need any help on it. Any teams intended for in-game and casual play should be posted in the In-Game Team Help sub-forum.
Semi-correct in singles, liable to get you killed in VGC doubles. Two at max and even then it's a bit iffy.
Have you thought about using Metagross? It's faster than most of your team sure, but it's usually slower than most of your opponent's team. Useful at absorbing dragon and ice attacks, and usually bulky enough to absorb just about everything else twice.
Normal Gem is a bit weird yeah, but if you can predict when an opponent WON'T use Protect or Wide Guard, you can possibly take out 2 Pokemon at once. Risky, but it's hard for the opponent to recover if you protect correctly.
