All of Rufio's abilities cost and grant gold to play. The profit margin is a lot bigger than the loss margin:

Q- combo at least 12

W- score 8 or above; there are 7 cards that give this right away, and there is a 5ish % chance to immideatley get a blackjack on activate

E- literally impossible to lose gold as hitting all ones gives a net profit of 0

R- rewards based on number of targets- placement yields great profit.

As his passive scales with the amount of gold he has, g/5 and g/10 items are super efficient with him, and careful play rewards him with not having to lose gold on death.
