Skirk Volcanist

Morph as a delivery mechanism for an instant-speed surprise: that is the trick this card is running, and it leans hard on the mountain-sacrifice clause to pay for the payoff. The face-up trigger throws three damage among up to three creatures, which means it can clear a token swarm, snipe a pair of utility creatures, or dump all three on a single fattie, all at the moment an opponent commits to a profitable attack. The cost is where the design gets pointed. The flip demands two Mountains off the battlefield, a deliberate red-deck tax that asks you to spend permanent resources for a one-shot board swing. That sacrifice is not incidental flavor: it caps how often you can lean on the effect and strips lands you were counting on to keep developing. The 3/1 body the card reveals is almost an afterthought, fragile enough to die to the same kind of damage it just dealt, which frames the whole thing as a removal spell wearing a creature costume rather than a creature with a bonus. As a snapshot of early goblin design, it captures the habit of stapling an aggressive payoff to a resource cost steep enough to keep it from being a default include.
