>>53625172I'd say get another attacker, like Gyarados, Vulpix, Kyurem, Calyrex, or any hard hitting water mon really. Lumineon is also a solid choice since you can actually attack with it. Also the obligatory Drapion if you have it.
Nest balls are just better than Basculin, don't take any bench space nor the attack for the turn. Not sure about VIP pass, you're not looking to set up a bench. If you want to keep them though, slot in 1 or 2 celebration Mew to better find them. Trecking shoes seem unnecessary too, you can already discard energy with Greninja and balls. Also capturing aroma shouldn't be neccessary with 4-4 nest-ultra balls. 1 energy search is enough, you already have Irida to grab it if necessary.
I'd go down on the Irida and Melony, put in some judge and research, Arven, Raihan, and maybe Miriam and Avery. If you do go with the Lumineon you can you use multiple 1-of to grab whenever.
Not sure about lake acuity, it's best used on top of radiant Gardevoir, and the deck obviously wants Greninja. Maybe try some temple and path?
Also add 1 or 2 energy.
