Iceberg Cancrix

A 0/4 wall that turns the snow supertype into a mill clock, which is a stranger job than it sounds. Most mill payoffs charge you for each card by naming a spell or an activated cost; this one taxes nothing except your willingness to build a snow-heavy board, then fires two cards off the top every time another snow permanent lands. Once the crab is down, every subsequent entry counts: a fetched Snow-Covered land, another snow creature, a snow artifact later. Each one is a trigger, and the count climbs passively while the crab just sits and blocks. That is the design elegance, wall stats fronting an engine that scales with your mana base rather than your spell count, but it is also the constraint, because the payoff only exists in a deck where nearly every permanent shares the snow supertype. It cannot be splashed; the mill is a byproduct of a wholesale deckbuilding commitment to snow, and outside that shell it does nothing but eat a Lightning Bolt worth of damage. The card belongs to the same design conversation as Hedron Crab, which mills on land drops: both attach an incremental clock to something you were already doing, but where Hedron Crab reads only lands, this one reads an entire supertype, opening the trigger to creatures and artifacts as well. The tradeoff is that you have to care about snow first and mill second.
