- Changes form before it's own move.
- Aegislash always comes out in Shield Forme. When switched out in Blade Forme, it will come in as Shield Forme.
- Damaging moves will change Aegislash to Blade Forme. Tested with Shadow Sneak/Shadow Claw/Cut/Aerial Ace.
- King's Shield will change Aegislash to Shield Forme.
- Non-damaging moves (besides King's Shield) will not change Forme. Test with Confide, Power Trick, Iron Defense, Autotomize, Swords Dance, and Protect do not change Formes. It will remain in whatever is was on. Tested on both Shield and Blade Formes.
- Aegislash will change into Blade Forme when using a move even if the move fails due to hitting itself in confusion.
- Stats for my Level 45 Aegislash (NOT BASE STATS). Shield Forme stats: 126/72/144/62/143/68. Blade Forme stats: 126/171/54/152/53/68. Base Stats still undergoing calculation.
