So here's the deck I used. In theory, it can beat everything, probably except Donphan. Damn Water weakness, lol.

With most of the real problem Pokemon banned already, there weren't many attackers left that could do huge amounts of damage. Miltank was one of them--80 damage in this format is a ton, especially for one Energy--but there weren't many Stage 2 Pokemon available for use. I couldn't afford to have them be just a Bench sitter, so they needed to be able to swing when I need them to and also have a low Retreat Cost to prevent stalling. Charizard GEN was banned, which left Bellossom AOR, Dustox ROS, Gardevoir RC1, Nidoqueen PRC, Serperior RC1, and Unfezant ROS #80. Dustox, Serperior, and Unfezant are all bad, so it was a choice between Bellossom, Gardevoir, and Nidoqueen. Nidoqueen is the strongest, but the huge Retreat Cost combined with the low number of Energy made it undesirable. Gardevoir is really weak, but Eternal Radiance is pretty cool in a format where most things can't kill Gardevoir in one hit. In the end, I decided on Bellossom. Bellossom not only has a low Retreat Cost, but its attacks are both pretty passable. One gets Miltank back up front, and the other redistributes my Energy in case I'm finna die. Eighty damage with a Band is pretty spiffy too.
Oddish and Gloom from BCR were used because they retreat for one. They also conveniently have a Resistance, and the others do not.
Silent Lab stops problematic Abilities like Energy Evolution, Propagation, Innards Out, More Poison, and Farewell Letter. It notably saved my ass in one of my matches by shutting Seviper off, allowing me to survive a turn and die going into my turn instead of his. Shout outs to that dude, that was my hardest match by far.
Lastly, the two PlusPower were meant to push Miltank's damage to 110, since that was the most damage I had ever expected to need to do. Of course, I didn't even know about Gogoat and its 120 HP, or
Donphan and its 130 HP god why wasn't this banned. I don't think it ever got me a KO but they were nice to have as insurance. In the future I probably wouldn't include them.
Anyway this is a meme meta so there's no point in going through matchups. Fighting Pokemon not called Donphan are colossally bad in this format so Miltank essentially has no Weakness. It has enough HP to survive a hit and is strong enough to take OHKOs for a single Energy, which is why I said that, in theory, it can beat just about anything. It's a fun deck and I'm not gonna complain about taking second with it.
