I Have the Answer to Mega Malamar

Instead of worrying about the Pokémon I had, I use new, awake ones

I use a Raichu for an Electric Terrain, which doesn't wake up sleeping Pokémon but prevents anymore from going to sleep

I use Umbreon and land Shadow Ball and Dark Pulse on your Metagross and Ceruledge

I use Cinderace for Pyro Ball on Metagross and High Jump K1ck on Zorua

Lastly, I let an Alpha Mega Lopunny just for cha0s

In case you don't know Alpha, it is larger than normal Pokémon and their stats are way better
