Z-boosted Nature's Madness (==> which becomes the move Guardian of Alola) always leaves the target with 25% HP (including Magearna, which is a very bulky check to Tapu Koko).
Then, a Thunderbolt in Electric Terrain finishes the job.
252 SpA Tapu Koko Thunderbolt vs. 248 HP / 8 SpD Assault Vest Magearna in Electric Terrain: 106-126 (29.2 - 34.7%) -- 6.8% chance to 3HKO
This is the
pivot set with Nature's Madness + Tapunium Z to overwhelm better its checks or bulky monsters in general for a useful team support. In this calculation I assume AV Magearna coming into play at 100% HP and stomaching a -75% HP on the switch. The lack of recover onto Magearna allows us to use even the regular Nature's Madness to achieve the KO.
The best part of Nature's Madness/Guardian of Alola is that they will alwayscut in half the opponent's HP, regardless of the boosts.
I'd like to underline that Nature's Madness is still very useful even without the Z-stone .
