Tier 1: Brett when he cares
Tier 2: Neo, Halo, Thallen, Ares, Highlander, maybe Exodus since he won a lot of OG Classic stuff
Tier 2.5: Clops, Deophite
Tier 3: Squirt, Zeross, Quick Strike, Prado, David, Jack, Trip, Crono, Enmity when he isn't being weird, Shadow (either one of them), maybe Clel, a bunch of others
...
Tier 9998: Warhawk, Macen, anyone with "Legendary" after their name, me when I had satellite internet for a year
Tier 9999: Tortoise

just my opinion, no particular order
