Soliton card art
Soliton untaps itself whenever it deals damage, which in the right shell means infinite activations without ever leaving the battlefield. The five-mana cost is real, but Kinnan, Bonder Prodigy cuts that down a step, and Mairsil, the Pretender doesn't even need to pay it — just cage the ability and go.

Mairsil, the Pretender cages Soliton to borrow its untap trigger, then pairs it with any tap outlet already on the cage to generate infinite activations — the ability is the whole point, and Mairsil gets it for free.

Soliton is legal in Commander, Legacy, Modern, Vintage, Pauper, and Oathbreaker, but Commander is where it actually matters. In 60-card formats the five-mana cost is too slow for any competitive shell and the payoff requires too much setup. Pauper is the one exception worth noting — Soliton is common, and any Pauper combo deck that can create a damage loop finds a willing partner here. Commander is the real home because the singleton rule doesn't punish a narrow card, the games go long enough to deploy it, and the combo payoffs scale to a format where one loop wins on the spot.

Price Context

Current price

$0.12 bulk tier

At $0.12, Soliton is firmly bulk — you'll find it in a commons box before you ever need to order it. Bulk combo pieces like this tend to stay flat; demand is narrow enough that no reprint pressure matters and no spike is coming.
