Ferrothorn counters this set fairly easily being able to just take thunderbolts and U-Turn while being completely immune to Toxic due to it's steel typing. This allows Ferrothorn to Set up his hazards against the opposing team, leech seed any mon that gets brought in after U-Turn, or just to Power Whip Tapu Koko in general.
