Fettergeist

A 3/4 flier for three mana is a body that should be overcosted, and the upkeep tax is the reason it isn't: this is a creature built to be the only one you control. Every other body on your side raises the ransom you pay each turn to keep it alive, which inverts the usual deckbuilding instinct. Most flying beaters want a team around them to capitalize on tempo; this one punishes you for fielding the team at all. The intended home is a build that goes wide nowhere and tall everywhere else: enchantments, equipment, planeswalkers, a control shell that wins with a single evasive threat and spends the rest of its mana on answers. The tax also doubles as a self-correcting clock against your own greed; flood the board and the geist eats itself on your next upkeep unless you can foot the bill. It is a rate that rewards a very specific skeleton and quietly taxes anyone who tries to slot it into a normal creature curve, which is exactly why it has always read better in theory than in the average deck. The design is honest about its trade: premium evasion and a hard-to-kill toughness, paid for with an ongoing fee that scales with your own ambitions on the battlefield.
