Most players want the sun, earth and moon for inferno.
To give you an idea, check out the other posts that show "my offer for
inferno" to give you an idea how much people are willing to give up for it.
I don't have anything really worth high value for it, unless someone willing
to trade inferno wants a Tomorrowland 8/9 pin as part of the trade.
I think that's the most valuable item I have in my inventory.
The more rare an item is, the more people are willing to trade it. They
also tend to prefer large quantities of items.
And of course, people with inferno would probably trade it for green flips
or green baggy pants in a heartbeat.
