Contaminated Drink

Card draw with a body count. The X here is doing double duty: it sets both the size of the refill and the accumulating rad counters, so the spell prices its own upside against a milling clock that scales with your greed. Rad counters grind your own library into your graveyard while feeding you damage on each triggered mill, which turns a five-card draw into a commitment rather than a free windfall. That inversion is the whole point of the mechanic: most blue draw spells ask how much mana you can spend, while this one asks how much long-term deck erosion you can absorb to spend it. The rounding is where the design pinches: half of X rounded up means the tax never fully disappears, and small draws are proportionally the worst deal, since drawing one card still saddles you with a rad counter. It rewards drawing large exactly once, then reading the board to decide whether you can survive the accumulated radiation, rather than being a reusable draw engine you lean on turn after turn. As a two-color instant that scales, it wants to be a midgame reload in a deck already flirting with self-mill or graveyard payoffs, where the rad counters are less a cost than a resource you were going to spend anyway.
