As expected, S. Rayquaza performs well in longer battles with Eevee. The restrictive nature of Rayquaza might be an issue for some, but I don't mind it at all, as it leads to more unconventional playstyles and emphasizes team building more than usual. As a reference, S. Rayquaza was dealing about 10k damage at the end of this battle with Dragon Ascent, and the same team with 3/5 EX Lunala was dealing the same amount, about 10k after 5 syncs.
The way I've seen people talk about S. Rayquaza will have you think that he is literally unusable and worse than Nate. Then again, this is the pokemon community we're dealing with. Not the brightest meeting of the minds.
