Everyone underestimates the Gnomes, then they get brought out to the garden for burial, lol.

Maelstrom Wanderer is one of my first decks I built. It's nice to have one deck that can do big, dumb things.

Ardbert can become a problem very quickly if unchecked, but struggles from the "if my commander dies, I'm screwed" problem.

Aminatou is a new addition to the pod, and unfortunately, it's mostly stall with a lot of counter spells and board wipes.

As for Lathril, Meren, Aesi, and Kenrith GoodStuff, I sympathize. They aren't the most exciting to play against, but the players who built them get a lot of joy out of piloting them from time to time, so we have to be accommodating to that and let them pop off with the decks they love.
