Why DDance on a Scarf Ray??
And Scarf maybe viable, but imo, DD LO is far more viable.
And uh Ho-Oh ain’t a Zac-C check those carry Wild Charge, a good check would be NDM / Quag.
Ho-Oh Toxic > Quake.
Substitute ESpeed Arceus’ ain’t used much, they would be hard countered by Defensive Xyg, go for Naughty Nat and Ice Beam, that also lets you past through Defensive MMence.
And Darm-Galatia’s is v bad...
Use Close Combat Zac-C > Sacred Sword.
