Make Ampharos your Mega. It needs to be a slow Volt Switcher that hits hard and you can always pass Wishes to it via Umbreon.
Crobat is your hazard management and Fairy check. Cross Poison, Brave Bird, Defog, U-Turn. Volt-Turn combo is pretty reliable for momentum.
Tyranitar is your Stealth Rock setter and Pursuit trapper. Try Lum Berry, Chople Berry, Leftovers, whatever.
Arcanine should be your physical wall imo but an offensive set is fine too. It's just that in my experience Arcanine is a fantastic wall considering Morning Sun and Will-O-Wisp. For an offensive set, maybe go with Choice Scarf or Life Orb or Assault Vest, packing Close Combat.
Espeon can be a special sweeper and/or a setup sweeper. Dual Screens support with Light Clay is also perfectly valid, and maybe you'd like it more actually to help your Wish support.
Umbreon is the central mon that everything goes back to. Run it as a mixed wall, or a special wall if you do decide to make Arcanine your physical wall. Wish Support, Heal Bell Support, Foul Play as your main attack. The last slot is filler: can be Protect, Toxic, Confuse Ray, etc.
