Looking for an OP10 Casual Unicornsplosion

I didn’t know the gun was one-per-character only when I redeemed it on OP8, and I would prefer not going through all that aggravation getting a second character up to OP10. I can negotiate a trade for any of the following at OP10.
World Burn
Rapid Infinity
Gunstock Maggie
Guileless Hellfire
Inflammable Flame of the Firehawk
