Pokemon Masters - Steven and Rayquaza (1/5, 1500 CS offtypes)
1) versus Agatha (special) - (0:00) - S. Rayquaza (1/5), Eevee (6EX, 3/5), Masquerain (3/5)
2) versus Bruno (physical) - (4:36) - S. Rayquaza (1/5), Eevee (6EX, 3/5), Torterra (3/5)
Now that I've had time to play around with S. Rayquaza, it looks like Good Form does not give as much of a boost as I would want it to. Although he can clear CS 1500 offtype at 1/5, it is not as easy as one would like. You really need top tier supports to go along with it, and you will likely be extending the battle with a focus on HP parameters, rather than going for the offensive parameters.
6EX Leaf is probably the best partner for S. Rayquaza, for quite obvious reasons. +12 stat boost on sync is very convenient. Lillie is also not bad because she also provides good buffs, but really you can just repeatedly sync with Leaf. Steven's main damage comes from Dragon Ascent, and you won't really sync with him too often.
It would be nice to test on a longer battle like Legendary Arena, but the only one running is Cresselia, and she sort of hard counters Rayquaza with Icy Wind guaranteed crit after each bar.
Certainly he seems like one of the weaker master fair units. Of course, he will still have a niche in some battles due to his passive, Downside Up, most notably in the Extreme Battle Event going on right now. I don't think I'll promote to 3/5 EX - he gets Weather Sync Up 9 and Fleet Feet which are nice, but not much else.
