Mutalith Vortex Beast

A gamble printed onto a body, with the odds scaling to the table. The coin flip is the load-bearing mechanic here: it runs once per opponent when the beast lands, and each flip is a self-contained bet where winning draws you a card and losing throws three damage at the player you flipped for. The upside and the downside both point at the same opponents, which is the design cleverness. A pod full of enemies means more cards to draw and more faces to burn, so the same trigger reads as pure advantage when the flips break your way and as a Grip of Chaos-flavored table-slap when they do not. Nobody at the table is safe from the payoff, and neither are you from the disappointment, since a bad run of flips leaves a six-mana 6/6 trampler that drew you nothing and merely poked a few people. That variance is the whole character of the card: it is not a value engine you can build around so much as a randomizer wearing a threat's clothes. The Warhammer chaos flavor is doing real work in the mechanic, not just the art; the ability is deliberately anti-planning, rewarding a player who is happy to hand the outcome to fate rather than one trying to sequence toward a guaranteed line.
