tried building around this on a whim since the replays in this post are from 2021. basically this is super good to pilot rn, takes advantage of the rising lele trend and breaks it over its nonexistent knees. this makes double ghost quite buildable, as you get to use a balance core that might not have a 100% lele matchup, and secure the winning matchup with aegi.This is an awesome discussion prompt, and I'd like to add my 2 cents into it after having done a lot of experimenting with weird stuff lately and watching SPL games to really help guide my thinking. So, I'd like to present: Aegislash, bar none the most slept on Pokemon in this tier.
A lot of my acquaintances are familiar with my stance on this Pokemon, and have endured quite a bit of discussion from me regarding it. It's a Pokemon that has had no tour breakout as of yet, but despite that, it is one I adamantly believe to be a presence in the metagame with untapped potential.
here's a recent replay, showing a team getting completely blanked by substitute: https://replay.pokemonshowdown.com/gen8ou-1517703865
one minor downside so far is that you're not necessarily faster than spdef lando, so chipping it down with repeated shadow balls is going to require some team support, but that's not really an issue as lando has been prime knock off/toxic bait since the beginning of the year. looking fwd to seeing more aegi on the ladder, it's incredibly slept on right now
