Hungry Mist

Six power for four mana, leashed to a rent payment: that's the bargain Hungry Mist offers, and the bargain it keeps clawing back. The recurring tax is the whole design. Every upkeep demands two more green mana or the body walks off the battlefield, so you never own the creature, you only lease it. What that structure really taxes is tempo, not raw mana: the per-turn payment doesn't shrink the body or dull the attack, it just keeps draining your development on every turn you want those six points on the board. The longer it sticks around, the less you can do alongside it. The two toughness is the second clamp, leaving an imposing front number fragile to any incidental burn or chump-and-block math. This is green aggression from a moment that priced its big attackers with deep suspicion, trusting an ongoing maintenance cost to police oversized stats more than the modern game does. The same conversation (how cheap can an outsized beater be before the upkeep has to bite) got revisited later with cleaner math and gentler terms. Hungry Mist's answer was to bite hard, starting the very turn after it lands.
