2-2-2 FFB Choice band EXP share 1 float stone? No poison barb, they can easily play around it.
No max potion. I get the thing you are trying to do with the "discard, then heal" but conserving energies is WAY to important without bronzong.
1 orangutu, but preferably Shaymin. If you need to late game ultra ball from N, pick up the item from genesect and ultra ball.
Bench space is too important, probably just play sky field to set up.
Genesect and Solgaleo might have trouble together. Any way you could focus on one, maybe run the other as more of a tech?
Energy retriever is a one of, or maybe none at all due to super rod. You should be fine with max elixir there.
Best to max out on consistency. X4 Vs seekers, ultra ball is better in that it can grab anything and Tapu Lele, so 4-2 on the poke ball line?
Why Pokémon ranger? I don't see a real problem that you need that card for.
Those are what I am thinking of off the top of my head. Sorry if it is a bit rough of my ideas are dumb, was just rattling them off. I would love to see this at a big tournament!
