Me and my friend Hoatzin would like to start something up.
Between us we have almost every card in the game.
If anyone would want to borrow any cards they would be able to.
But we would charge a 10% of the cards price as interest each week it was borrowed.
This has been done in guilds before, and usually goes well. Typically there isn't an interest on cards lent out. Nonetheless, this is really open to scam despite being players that you deem trustworthy.
