But to Zard-Y in particular, why would you use this above special Primal-Groudon? The tiny jump in speed, not enough to outspeed fast Arceus-formes doesn´t really seem attractive enough.
And a thing with the posted team, Zard-Y has drought on its own, why even forego PDon? You are just left with a strong attacker with no defensive utility whatsoever and 4times Rocks weakness that can´t dent Kyogre coming in on it, made worse in your team by not even having a PDon.
I think if you want to convince people of "unique" mons like Zard-Y, "Charizard-Mega-Y is an amazing fire type and is potent when used correctly." isn´t going to cut it. Provide some detailed insight why you would pick that apart from having fun.
