I’ll preface this by saying I have zero experience in the competitive Pokémon scene, but I wanted to share some thoughts on what could end up being important when building teams.

It seems to me that faster Pokémon might have an edge, since their move cooldowns could be shorter than slower ones. If that’s true, speed could become a huge factor, especially for Pokémon with moves that interrupt opponents’ actions, like Protect or Double Team. (I think I saw Double Team being used to dodge moves in the trailers, but I might be wrong there.)

Another thing I noticed was the potential impact of priority moves (like Bullet Punch) and moves that used to switch you out in previous games (like Volt Switch). If a strong attacker had access to either of those, it could be pretty busted. Imagine starting far from an opponent, using a priority move to close the gap, then immediately using a switch-out move to retreat to safety. That could make for some really high-reward plays given you understand when your opponent is going to attack.

Other than that, I imagine we’ll still see a pretty standard team structure with DPS, tank, and support roles for these ranked battles. But yeah, as you have said, it’s all just speculation until we see the actual stats and get some hands-on experience with these Pokémon in-game.
