Well, FWIW, I just finished my
exercising testing with the Sun team I built. Got 7 games in within an hour and a halfish. 6 of those games were Little Timmy Ubers players.
I went undefeated. 7-0-0, saw most of the Ubers tier being played with the only ones I didn't run into being Bundle, Stone, Cyc, Espa, and funni fish. I even had a Sun mirror match that was... Interesting to play. I won because my Hat got to +2 and lived damage roll on 1.
Some notes from my time:
1. Wake is an absolute MONSTER. Like, this thing is NOT okay lmfao. You absolutely blow things up with Sun boosted Specs Hydro Steams, and forget about the Draco damage. I only Terastalized it once, and that was to ensure it didn't die to Dragapult randomly. (Seriously, you outpace non-Scarf Pult by a mile with Proto Speed Timid.)
2. Torkoal is kind of a sitting duck most of the time. Even with max SpAtk it just didn't quite do a whole lot outside of burning a duck and setting the Sun. I might try throwing Rocks onto it too so I have 2 rockers.
3. Unga Bunga Boongus over here hits like a TRUCK. Sucker Punch was a very useful utility against a couple of Pokemon, and Bullet Seed just sort of nuked a few things. I also learned that it outpaces defensive Sylveon, which was nice.
4. I only "had" to Tera like... 3 times, and 2 of those were on Dengo itself. I guess the coverage on Wake isn't necessary at all with the absolute Fat Man Mini Nuke of a Pokemon we have here. Seriously, it one-shot a Fluttermane.
5. Grass Wake didn't really show up often as a necessity. Maybe Steel would've been the better pick, to snipe the most common Fairies.
6. Tusk is a beast of a tank under Proto, and I don't know if I want to keep my Hat as a Phys Def CM set or a full SpDef set.
7. I could probably see Wake getting axed. This thing is just too strong.
