I would run 4 ST T-tars, it eliminates the need for the multi energies. I'd recommend the Weavile that searches out Dark energy, and special darks are a must.
I've heard a lot of good stuff about Turtwig GL. I goes great with Kazam X, Shaymin X, and Cherrim. But will it be viable in actual play? Would it be too difficult to set up the bench for it? Thanks in advance!
The Eeveelutions out of RR make eevee easier to run without implementing a new rule to the game. The ability to search out eeveelutions, as well as a reusable Eevee make up for it.
