You'll go through teh same pattern I experienced;

You'll hit the 1:1s or super-rares with one sold unusuals, then move on to low-tiers (like Bubbling, Steaming, Nuts stuff)

Then you'll gradually move to Mid-tiers (Cauldron Bubbles Stahlhelm, other Halloween stuff)

Then you'll get into Pricing Duped Bonk Boys and Crone's Domes lol

I wish you luck, 'twas my path to become an Unusual suggestor
