Me too! I know it’s all because
420LegitShucks did a great job researching the matter. You can view that
here. I initially didn’t want to spoil the announcement but I feel like some people would want the context for the acknowledgement, in case
The Immortal has wanted to be seen first.
Ultimately, I feel it will be they both will be the great check (offensively Galar), and counter (defensively Unova) to the doggos bc it can either KO, or single-handledly resist all of their STABs, while threatening with its own STAB.
I hope to put them to good use.
Lastly, I like your sets. For someone who recently joined us, I am glad you came up with helpful and very strong utility even against Imposter.
Externatus with RegenVest doesn’t just seem to work well, it makes very good sense, as the fall of Psychic attackers & attacks, weakening of Ground moves, and high Speed allow it to escape very well without coming in on a hit and being afraid of going last to tank 1 too many (like if the foe has a surprise coverage move).
For Solgaleo maybe a good set would be Prankster / Magic Bounce:
Spectral Thief, Roost, Anchor Shot, Entrainment / Poison Fang.
This allows you to Imposterproof your Zekrom, if it fell below 80% HP, as they Multi-Attack on your switch, which you resist. When they try and Boomburst, they get Entrained so you resist that too (and they lose STAB). Spectral Thief disarms their Shell Smash, and works off of Solgaleo’s workable Attack.
Otherwise I would consider for a Magic Bounce set - Poison Fang for accumulating damage while a foe are trapped. Roost keeps you safe, while Magic Bounce also blocks Hazards, Status attacks, etc. Magic Bounce still stops Entrainment.
This also works well if Imposter switches into it, (you can trap and wear down their PP until they struggle), and can play a major role on a team in general. Solgaleo doesn’t need to be offensive, it can take the offensive boosts away as a defensive check and then bring the power from Spectral Thief.
This also works well as a stop to Dragapult’s Normalize shenanigans. You Entrain first via Prankster as they try and Entrain, and if they try and set up you can Spectral for super effective damage. Since it is a Ghost, you cannot trap, so when they switch out you can Poison Fang their switch-in, only for them to have a 50% chance of being Toxic Poisoned. ;)
Once they see you have Spectral Thief, the will avoid sending in set uppers that are not the Normal-type, and if you have Magic Bounce they cannot try and use status moves or hazards. Be careful of Scald, though, still you handle most things while resisting SRocks, and being immune to Toxic Spikes.
