Non king shield aegis is legit. Normally using HPice or a weird headsmash with a lifeorb or a CB. Uncommon but effective against some switch ins.You can laugh all you want, but I can pull off delphox in OU. No one expects magic coat, so if I start with it, they can't get any entry hazards in.
I've seen a bit, like an aegislash without King's shield. That one really confused me.
And yep no one expects delphox. I have stolen leftovers AVs and Eviolites left and rugth with Solarbeam power herb.
