Due to Deoxys's main series stats, all formes are actually unaffected defensively by the rebalance. The HP buff doesn't apply to raid bosses so its extra HP won't be a factor here. Unless they give it the "Tier 6" treatment they gave Mewtwo during its month of normal raid battles it will be an even easier solo than projected due to your own Pokemon getting bulk buffs.

Deoxys atk form solo?
Hey! I know the attack form of deoxys was soloable before the HP rework..
I'm curious if it's still possible, now that HP and defense have been recalculated.
Thanks in advance!
