Espeon: Espeon's ability to inflict Confusion, among other status spells, is potentially a problem, which is why Shinobu is arming Mochi with a Persim Berry and sending them out to inflict Taunt. Mochi also has Double Team at their disposal, and will be using that to up their evasion and Hone Claws to up their attack and accuracy. After that, it's time to exploit Espeon's weakness to Ghost and Dark attacks by breaking out moves like Shadow Claw and (courtesy of a fortuitous TM delivery) Dark Pulse - mostly the former, as Mochi gets STAB with it. Mochi will also keep reapplying Taunt as needed, and if things somehow turn against them will break out Destiny Bond. Hopefully that last won't be necessary, though.
Mr. Mime: If Mochi is still hanging in there, they may start this battle off, using the usual Taunt -> stat buffs -> offensive moves -> Taunt -> repeat strategy. However, Mochi only has a couple of levels over Espeon and only one over Mr. Mime, so it's not unlikely that they'll be tiring at some point. And while Shinobu really doesn't like bringing in very overpowered pokemon (it doesn't seem fair to the gyms' pokemon), he doesn't really have much choice at this point. So he's bringing in Kanchou to take advantage of Mr. Mime's weakness to Steel. He's not going to be buffing himself too much - he doesn't have Taunt, so Mochi may need to switch back in to apply it, and there's little point in drawing the battle out by re-applying stat buffs - but at level 78 and with Metal Claw and Flash Cannon to take advantage of Mr. Mime's weakness to Steel (and the STAB Kanchou gets with both of those attack moves), he may not need the buffs.
Alakazam: The strategy here is roughly similar to that deployed against Espeon: Arashi comes out armed with a Persim Berry, opens with Taunt to shut down Alakazam's status moves, and then proceeds to buff themself/debuff Alakazam and then go for the offensive moves, with periodic reapplications of Taunt as necessary. In Arashi's case, those offensive moves are Aura Wheel (during those turns when it's Dark element, anyway), Crunch, and - if Alakazam manages to use a debuff on Arashi despite everything - Lash Out. As a level 78 pokemon with partial Dark typing, Arashi has a significant advantage over Alakazam, so it seems likely that the Morpeko will prevail relatively easily, but if things do manage to go sideways, Akari is waiting in the wings with her own arsenal of STAB moves (and Taunt). Given that Akari is level 99, hopefully it won't come to that.

Shinobu, as ever, is his pokemons' item caddy.
