I may be biased in saying this, but I honestly do feel Deoxys VSTAR’s extra effect for its main attack is better than Zeraora VSTAR’s in my opinion. Zeraora discarding Stadiums is neat and all, whereas Deoxys at least guarantees that if your opponent has a benched V, you can get a 60 sniped on it. Not worth a Telescopic Sight, but Psy Jav at least 3HKOs Crobat and Lumineon, which can be Volo’d even so.
I do feel Zeraora would benefit for being a Rapid Strike, but the only problem is that Rapid Strike Energy wouldn’t really help it and there isn’t really any Rapid Strike tech to assist Electric that I remember at the moment. Flaaffy is pretty much the only Pokémon support I remember, alongside Stormy Mountain as a Stadium.
Zeraora VSTAR’s decent, I’d say.
