Well, you need to take a Knock Off to the face anyways. As for the EV spread, i will share my personal favorite (made by me 3 monts ago). Relaxed Nature (innovation n_n) with 44 Defense (gives Sharps little chance to KO you), 100 Sp.Def (allows Specs Modest Hydreigon to have a slighty bigger chance to KO you) and 108 Sp.Atk (2HKO sylveon, a thing that already did with max sp.atk).
Calcs are here:
- 108 SpA Aegislash-Blade Flash Cannon vs. 252 HP / 100 SpD Sylveon: 102-122 (50.4 - 60.3%) -- guaranteed 2HKO
- 252+ SpA Choice Specs Hydreigon Dark Pulse vs. 252 HP / 100 SpD Aegislash-Shield: 144-170 (86.2 - 101.7%) -- 12.5% chance to OHKO
- 252+ Atk Life Orb Bisharp Knock Off (97.5 BP) vs. 252 HP / 44+ Def Aegislash-Shield: 143-172 (85.6 - 102.9%) -- 6.3% chance to OHKO
Sounds good! :) I will definitely credit the spread to you once I start using Aegislash for reals and update RMT.
By the way, with 252/44/108/100, you're missing 4 EVs :O
