Flip a fair coin, heads half the time. Heads: for your next two draft offers you take every card instead of one, and your next offer rolls a tier higher. Tails: both you and your opponent skip your next draft, but your following offer still rolls a tier higher.
You draft Gamble in Buff mode. Instant: it takes effect the moment you draft it.
As a draft card, it bends one player's draft: the tier, the count, or the pool.
“Heads you win, tails you win a little.”
