Note that the opponent could just sack koko and go to lucha, as even tho 1 out of 16 rolls from unburdened acrobatics would land the KO, mega scizor would be able to pick the game back with BP, and this is something no prediction will be able to save, due to the fact that +1 blacephalon is still slower than an unburdened hawlucha. Besides, there's practically no risk in doing so, the cost and reward for the opponent will be consistent, since no matter the blacephalon set is used, the counterplay will still have the same effect.
Blacephalon @ Ghostium Z
Ability: Beast Boost
EVs: 236 HP / 20 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Flamethrower
- Shadow Ball
- Calm Mind
- Substitute
Essentially, you pivot into Mega Scizor and setup a Subsitute and one Calm Mind; this allows you to not only get enough special attack to somewhat OHKO the entire core but also make yourself immune to any sort of priority (except Water Shuriken) for a good amount of time. After OHKOing Mega Scizor, you gain enough speed to outpace Tapu Koko since it needs to come in before Hawlucha to activate Unburden. Considering you have a chance to not OHKO without using the Z-Move on both Hawlucha and Tapu Koko, you basically want to have it for Hawlucha and because you have a Substitute up, you will survive Tapu Koko. After taking out both Mega Scizor and Tapu Koko, you have enough speed to take out Hawlucha and you've successfully taken out the core with minor chip from Substitute recoil and a potential Bullet Punch.
