U mean leader, if u do, i'll take it 4 ur credits, and all coins, it's Ambre, lvl 5
You need a star, to do get 1 you need to bu credit
Humm mister moo you can't trade credits, only code
Karker you can buy one on the market, but you have to level it up (it's long for a leader)
But you can buy a maxed one from someone on the board.
You don't need to buy credits to buy cards, only to sell
