I'd think Sunny Day would be better than Work Up. Why give yourself a 50% boost, when you could give yourself 2 boosts? (1 from Solar Power, and Flamethrower's sun boost)
It doesn't resist Dragon Pulse.
Since it's available now, is Galarian Slowpoke going to be allowed immediately? Or do we have to wait for its evolved forms to be released?
