Re-suggesting with proper prices. Apologies.

Decided to try to price this since I forgot to when I bought it.

Sale #1: Sold for a White Lightning Blast Defense (25) and a Professional KS Australium Force of Nature (13.1) = 38.1

Sale #2: Sold for a Searing Plasma Hustler's Hallmark (49) and a Potassium Bonnet (12.1) = 61.1

Mini on the Hustler's: Sold alongside a Vivid Plasma Millennial Mercenary (46) for a Omniscient Orb Patriot Peak (95)

Additionally, there was this sale that was a bulk sale and had a bunch of outdated and unpriced messiness. Without touching the unpriced and seemingly-bugged war paints, and not performing minis, the sale comes out to value the Blast Defense at roughly 65 keys. Not a usable sale in that state, but figured it would be valuable supporting evidence to indicate the 61.1 isn't an outlier.

Thanks, let me know if I missed anything!
