Martyr of Frost

A soft counter that walks onto the board first, then asks for an escalating tax: the more blue cards you flash from hand, the steeper the price to push a spell through. The trade is information for leverage. To make the counter bite, you reveal X blue cards, which tells your opponent exactly what you are holding before they decide whether to pay the ; the tax is only as large as the hand you are willing to expose. That self-disclosure is the cost that balances a one-mana body able to neutralize almost anything late, when X climbs high enough that paying becomes prohibitive. It belongs to a cycle of one-drops whose abilities all key off revealing cards of a particular color and then sacrificing the body, the same structural template stretched across the colors. As a permanent that becomes a counterspell, it dodges the central weakness of a soft counter held in hand: it survives discard, sits on the board as a 1/1 chump or pressure until you need it, and can be sandbagged across turns rather than committed to a single window. The catch is timing, since the activation costs on top of the body already in play, so the counter you want at instant speed has a real mana floor underneath it.
