I've been having very mixed success against non-GX decks lately playing Metagross GX, even when I set up fairly well. This is against decks like Mach Strike x2, baby Metagross, Alolan Exeggutor, etc., which I had a lot of trouble against (1-2 against those 3 decks). I'm pretty familiar with how to play against the meta decks (i.e., BuzzRoc, ZorGarb, etc.), but I seem to struggle getting 6 KOs against these (or 5, since most of the time there's a Lele out there to grab 2 with at least). I feel like Metagross should have a _huge_ advantage over non-GX decks (since mostly they just can't compete with 250 hp), but I've really struggled, so I must be doing something wrong.
In general my strategy is to get my 3 Metagross built up quickly, and then just rotate and make sure I'm absorbing the hits, using Max Potions to clear out my hp when I take a hit, and make sure to have Dhelmise out there if it's a 160hp deck (like Eggie). I Guzma into their tech cards when I can, and try to keep my hand fresh. I'll even try to get Ultra Necrozma out pretty early and try for those 100hp KOs with just the two energy when they've got a weak tech card out there (or, say, a baby Egg).
Anything I'm missing? (Either specific to Metagross or just general strategy against these decks)?
