Supreme Phantom

Spirit tribal lived and died on its anthems, and the math here is what made the deck a clock rather than a pile of evasive ones and twos. A two-drop that buffs every other Spirit is the cheapest entry point a flying tribe could ask for, and the body carries as much weight as the bonus: a 1/3 shrugs off the small pings and X/1 sweepers that would otherwise prune a board of fragile fliers, so the anthem keeps working through the turns when it is doing the most lifting. Stacking a second copy doubles the rate, and because the buff hits toughness as well as power, a board of one-toughness Spirits suddenly stops dying to the incidental damage that keeps most aggressive flyer decks honest. The lineage runs older than the printing suggests: white had Spirit anthems for years, but putting the effect on a blue flier gave the tribe an evasive second-color home and a reason to build around the air as the win condition rather than as a tempo footnote. Even drawn late, with no other Spirits down, it is still a flying blocker that will pay off whatever comes next, so the anthem's usual weakness (dead in a vacuum) never fully applies. This is the piece that turned a collection of evasive creatures into a deck.
