Don't forget, if we get the right homage we might have great use for a
Deoxys EX; actually, if they get the proper "pumping up" and "updated references", they all look like they have great potential.
General things to consider is that the various "forms" had between 90 and 110 HP, and classical Pokémon-ex didn't break 120 HP if they were only Basic Pokémon, and that while it is possible the homage route will be ignored or butchered, things actually look pretty promising.
Deoxys ex (
EX: Deoxys 97/107), a.k.a. "Normal Forme" has a half strength X-Ball style move, though with a less effective price. It is entirely possible they make it a "nerfed"
Mewtwo EX... nerfed save for having Form Change... and that could still be well worthwhile.
Deoxys ex (
EX: Deoxys 98/107), a.k.a. "Defense Forme" oddly has the lowest HP, but the effect of its (easy to pay by modern standards) attack is 50 damage and blocking the effects and damage of attacks from Pokémon EX. If the HP and damage done come up enough, its an alternative to
Sigilyph.
Deoxys ex (
EX: Deoxys 99/107), a.k.a. "Attack Forme" has an expensive version of X-Ball... but the differences could make that worth it if, as usual, it is appropriately updated and upgraded.
Deoxys ex (
EX: Emerald 73/106) a.k.a. "Speed Forme" has what would an attack that ignores all effects on the Defending Pokémon
plus Resistance, hitting for a then great 50 damage for three. Again, if they supersize this and just make the minimal wording updates, quite useful.
