Spell Syphon

A counterspell whose tax scales not with the spell it answers but with the depth of your own blue board. The more blue permanents you control, the steeper the price the opponent must pay to push their spell through, which inverts the usual two-mana counter math: it does nothing on an empty board and grows brutal once the count climbs past three or four. This is a payoff for heavily blue builds rather than a generic answer, a soft counter the controller can theoretically pay around but rarely will once the tax is real. Like Mana Leak, it trades a guarantee for efficiency by asking the opponent to spend mana they would rather not; the difference is that Mana Leak charges a flat , while this charges a number you set by how many blue permanents you have on the battlefield. The crucial detail is what feeds that number: lands are colorless, so your Islands contribute nothing unless an effect paints them blue. What raises the tax is any blue permanent you control—creatures, artifacts, enchantments, planeswalkers, or lands turned blue. And because the count is read off the board at the moment of resolution, the friction worth watching is timing: a blue creature dying in response, or a removal spell traded into the window, shifts the figure. It rewards firing into a stable board and punishes the player who casts it on an empty one. Stack enough blue permanents, and it asks a question opponents usually cannot afford to answer.
