252+ SpA Choice Specs Tapu Lele Hidden Power Fire vs. 252 HP / 252+ SpD Ferrothorn: 152-180 (83.9 - 99.4%) -- guaranteed 2HKO3) Ferrothorn as tank/stall. It can take tapus (except HP fire lele). But if my statement (1) is true, then I think that FWG cores or the Azumarill + Ferro + dragon, making the fairy-steel-dragon core, be common too.
like I could honestly see some people
using Occa Berry Ferro to catch it lol.
