Future Sight is a big no on Alakazam because it takes 2 turns to fully execute. It also needs Focus Blast to reliably damage Steels:
-Psychic
-Shadow Ball
-Focus Blast
-Encore/Thunder Wave/Dazzling Gleam
Nature: Timid
EVs: 4 HP/252 SAtk/252 Spe
Item: Focus Sash
Ability: Magic Guard
Crawdaunt functions best in teams that utilize dual screens or Sticky Web, given how slow and frail it is. It's also a bit too slow for Dragon Dance. Dragalge is a better Adaptability abuser (due to its better bulk); it also provides a Fighting resistance. That type is what shreds through this team now; stuff like Breloom and Conkeldurr can rip through it pretty easily:
-Sludge Wave
-Draco Meteor
-Scald/Hidden Power (Fire)
-Focus Blast/Hidden Power (Fire)
Nature: Modest
EVs: 200 HP/240 SAtk/12 SDef/56 Spe
Item: Choice Specs/Dragon Fang/Poison Barb/Toxic Plate/Draco Plate
Ability: Adaptability
Simply put, Mega Audino is
the most underwhelming Mega introduced in OR/AS. Its useless ability in singles and its significantly lower offensive presence compared to its fellow Megas is why people shy away from it. The Fairy Megas to go to in this case are Altaria, Gardevoir and Diancie who have more offensive presence and good utility options:
Altaria:
-Dragon Dance
-Return
-Earthquake
-Roost/Fire Blast
Nature: Adamant
EVs: 252 Atk/4 Def/252 Spe
Item: Altarianite
Ability: Natural Cure
or
-Hyper Voice
-Fire Blast
-Earthquake/Heal Bell
-Roost
Nature: Timid/Modest
EVs: 24 HP/248 SAtk/236 Spe
Item: Altarianite
Ability: Natural Cure
or
-Dragon Dance
-Return
-Earthquake/Heal Bell/Substitute
-Roost
Nature: Impish
EVs: 248 HP/136 Def/96 SDef/28 Spe
Item: Altarianite
Ability: Natural Cure
or
-Return/Hyper Voice
-Earthquake/Flamethrower/Perish Song
-Heal Bell
-Roost
Nature: Impish/Bold
EVs: 248 HP/104 Def/156 SDef
Item: Altarianite
Ability: Natural Cure
Gardevoir:
-Psyshock
-Hyper Voice
-Focus Blast
-Taunt/Will-o-Wisp/Calm Mind
Nature: Timid/Modest
EVs: 24 Def/232 SAtk/252 Spe
Item: Gardevoirite
Ability: Trace
Diancie:
-Rock Polish
-Diamond Storm
-Moonblast
-Earth Power/Hidden Power (Fire)
Nature: Rash
EVs: 64 HP/16 Atk/252 SAtk/176 Spe
Item: Diancite
or
-Calm Mind
-Moonblast
-Earth Power
-Psyshock/Hidden Power (Fire)
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Diancite
or
-Diamond Storm
-Moonblast
-Earth Power/Hidden Power (Fire)
-Stealth Rock/Hidden Power (Fire)
Nature: Naive
EVs: 16 Atk/240 SAtk/252 Spe
Item: Diancite
If you want a Normal Mega, use Lopunny, or even Pidgeot if you're feeling gutsy enough:
Lopunny:
-Fake Out
-Return
-High Jump Kick
-Ice Punch/Toxic/Healing Wish
Nature: Jolly
EVs: 252 Atk/4 Def/252 Spe
Item: Lopunnite
Ability: Limber
or
-Substitute
-Return
-High Jump Kick/Drain Punch
-Encore/Drain Punch/Baton Pass
Nature: Jolly
EVs: 252 Atk/4 Def/252 Spe
Item: Lopunnite
Ability: Limber
or
-Return
-High Jump Kick
-Power-Up Punch
-Encore/Heal Bell/Substitute
Nature: Jolly
EVs: 252 Atk/4 Def/252 Spe
Item: Lopunnite
Ability: Limber
Pidgeot:
-Hurricane
-Heat Wave
-U-turn
-Roost/Hyper Beam
Nature: Timid
EVs: 252 SAtk/4 SDef/252 Spe
Item: Pidgeotite
(note: Hyper Beam is a thing on Mega Pidgeot not only because of its lack of other good options, but also as a last-ditch resort to heavily damage or KO something when it's on its last legs)
Cincinno and Ambipom aren't good because mono-Normal rarely achieves much, plus they're frail. Magnezone is a good fit for trapping and KOing Steels.
