I decided to give an anwser for my old self. And here's the conclusion I made.
Muk-Alolan is able check it cause of Assualt Vest. With it, Muk can avoid 2HKOs from Moonblast and Focus Blast and then OHKO it with a Poison Jab.
I messed with the Showdown damage calculator and realised that Tapu Koko and OHKO Defensive/Calm Mind Tapu Fini with Thunderbolt in Electric Terrain as Long as I bring in Tapu Koko safely. A taunt is also helpful.
Pheromosa is able outspeed and OHKO it with Poison Jab as Astronautical mentioned above. Scarfed Landorus/Garchomp is also able to OHKO it with a Earthquake.
Marowak-A is a solid check to Bulu being able to resist its STAB and other moves. A poison move is also able to bring it down.
And that's done. I realised that I need to depend on different mon to check them, not just only one. I will be removing this from the non selected anwser question section.
