Move description and who already knows it

Find it yourself
Why?
Aura sphere is a special fighting type move. It is a better focus blast. I think a lot of pokemon should getthis as focus blast is unaccurate. For example gengar, it needs focus blast to hit tyranitar and lucario. But sometimes it misses and you can get swept. That is why you need accuracy. It also helps against double teamers,sand veil and brightpowder
Nominations to get it.
Gengar- As mentioned above, gengar loves the accuracy boost which means it can beat ttar and lucario easily.
Blazieken- This would be a grat special stab,as they switch in their physical wall they take a aura sphere of base 110 SAttk
Infernape- See above
Kerudio- This move would be good on sets that are mixed and don't want to run sword of mystery
Meloetta-Same as gengar
Mismagius-Same as gengar but not relying on a hidden power
Alakazam- same as gengar
Jynx-same as gengar
Lati twins- Gives them a reliable and powerful stab moves to beat steels without relying on hp fire
Deoxys- Deoxys is a alien Nuff said
Victini- same as gengar
Rankurusu-same as gengar
Shandeera- Same as mismagius without lucario.
Edit:
Medicham should get it because it is psychic and fighting, it meditates, it's ability is pure power, which reminds me of aura, it has a sixth sense, and this pokedex entry from the anime, "Through a combination of food deprivation and meditation, Medicham gains the ability to see its opponent's aura."
