Blood Sun

A hoser aimed at the part of the manabase players forget can be attacked: not the mana a land taps for, but everything else it does. Strip a land of all abilities except mana abilities and a creature-land stops being a creature, a fetchland stops fetching, a Field of the Dead stops counting bodies, and a bristling utility land collapses into something that makes the right color and nothing else. The line worth dwelling on is which abilities survive: mana abilities are untouched, so this punishes lands for their text without denying anyone the ability to cast spells. That is what separates a scalpel from a hammer; it does not choke the opponent's mana development, it deletes the value engines bolted onto the mana. The cantrip on entry means it is never a dead draw, trading itself for a fresh card even in the worst case while its static effect goes to work immediately. The catch is that the effect is symmetric: it silences your own lands' nonmana text just as thoroughly, so it rewards a build whose manabase asks nothing more of its lands than color and quantity. Within that discipline it is among the sharper answers ever printed to the slow accumulation of value that utility lands provide, hitting the whole category at once rather than one land at a time.
