Hi everyone,
Here's a variant of the Substitute + King's Shield set, I saw it first in a Lord Emvee's video on youtube and it worked out pretty nicely in lots of games :
Sub + King's Shield
Aegislash @ Leftovers
Ability: Stance Change
EVs: 240 HP / 252 SpA / 16 Spe
Modest Nature
IVs: 0 Attack
- Substitute
- Flash Cannon
- Shadow Ball
- King's Shield
Moves
Substitute gains Aegislash free attacking turns against Pokemon that are incapable of breaking its Substitute with one attack, such as Toxapex, non-Knock Off Ferrothorn, Jellicent and Corviknight. Once behind the Substitute, Aegislash turns into an offensive threat that deals a good amount of damage to all the OU metagame while acting as a decent wall-breaker thanks to Shadow Ball's and Flash Cannon's ability to drop the foes' Sp.Def.
Flash Cannon and Shadow Ball are two stong STABS that neutrally hit all the OU metagame. In this set, Flash Cannon is prefered over Sacred Sword to super-effectively hit Fairy-Types and OHKO Hatterene after Stealth Rock damage. King's shield is mandatory on Aegislash letting it go back into Shield Form, regain its defensive stats, scout for moves, gain an extra turn of Leftovers recovery and drop the physical threats' Attack.
Set Details
240 HP EVs ensure Aegislash avoids the OHKO from Modest Specs Dragapult's Shadow Ball in Shield Form. Maximum Sp.Attack investment and a modest nature allow Aegislash to hit as hard as possible and progressively break through common defensive Pokemon. 16 Speed EVs allow Aegislash to constently outspeed uninvested 60 and 61 BS Speed Pokemon such as Clefable and Tyranitar. However Aegislash can opt for a 64 Speed EVs investment in order to outspeed uninvested Corviknight but it exposes Aegislash to a potential OHKO from Timid Specs Dragapult's Shadow Ball. Leftovers give Aegislash more opportunities to use substitute throughout the game and pair well with King's Shield.
Usage Tips
Due to its low tier speed, Aegislash's needs a Substitute to get its job done, its priority should be to set up a Substitute against Pokemon that it forces out or Pokemon that can't break its Substitute, such as Corviknight, non-Night Shade Jellicent and Toxapex. Once behind a Substitute, Aegislash's combination of STABS and its unique access to King's Shield should be used to progressively wear down foes and check the potential choice locked incoming threats such as Dragapult or Galarian Darmanitan. Entry hazards help a lot Aegislash in progressively wearing down opposing Pokemon, try to always keep them up on the field. Thanks to it's great typing, Aegislash only takes few damages from Stealth Rock which maximise its ability to switch in pokemon it can beat. Leech seed and paralysis-statu hinder Aegislash's ability to damage foes or break through defensive Pokemon, try not to switch into these moves and avoid them with Substitute whenever possible.
