Champion battle

I’ve been stuck against Reukra for some time and I don’t know what to do, I’m currently trying to beat him using D. Haxorus too

My team:

D. Haxorus (Metal Coat)
-Aqua Tail
-Iron Head
-Crunch
-Swords Dance

Giratina (Spell Tag)
-Aura Sphere
-Shadow Claw
-Shadow Force
-Hex

D. Bisharp (Nothing)
-Drain Punch
-Power Up Punch
-Blaze Kick
-Aerial Ace

Mega Eevie (You can figure this out)
-Moonblast
-Hydro Pump
-Thunderbolt
-Leaf Blade

D. Scizor (Scarfed)
-Night Slash
-Drain Punch
-Icicle Crash
-Hail (Probably gonna swich this for another move)

Mew (Leftovers)
-Psychic
-Fly
-Aura Sphere
-Calm mind

(Everyone is lv 88)

well, you should first of all, level everyone up, there to low, and if you use a delta gardevoir, you can set up on the champions kyurem, and sweep his entire team from there.

I dont have delta gardevoir, Only D. Gallade

The elite 4 and champion’s pokemon’s level are around the level of you party’s higest level, but thanks, I’ll try

well as long as you can paralyze the kyurem, and u have calm mind, it will work, or you can use another set up move.
