This unusual has barely been touched, and the price for this is 5-6 months old.

The first link has offers exceeding the range the unusual has various offers on it, before it was given away to the person in the second link. Some notable offers on the Pyromancer, with all prices according to Backpack.tf:

1 bud 1 bills (35 keys/1.3 buds) (2 weeks ago)

Stormy Napper's Respite (1.5-1.9 buds)

Haunted Prancer's Pride (1.1-1.3 buds)

The person trading this hat notes he has gotten 1 bud offers easily for this,

The second link shows it being sold for a Green Confetti Gonzaga, and a Strange Festive Huntsman, within the past week.Using the 16-20 key price tag for the Gonzaga and the 16-17 key price tag, with both prices according to Backpack.tf, the 32-37 keys it sold for far exceeds the measly 18-23 key price tag it currently has, making it necessary for a price change. Note again that there are more offers in that link that have a 1 bud offer and a 24 key offer.

Hopefully, the links and the information are adequate enough for a price change for this hat.
