Symmetry Sage

The trick this design pulls is turning a defensive body into an offensive threat without ever touching toughness. A magecraft trigger sets a creature's base power to 2, which means the number you land on is not additive but declarative: cast a second spell in a turn and the second trigger simply re-sets base power to 2 again, overwriting rather than stacking. That overwrite behavior is the wrinkle worth internalizing, because it also means this evasive 0/2 can point the buff at itself and swing for 2 in the air, or hand the boost to a token or a hexproof creature it wants pushing damage. Base-power setting interacts cleanly with anything that adds power on top (+1/+1 counters, anthems, pump), since those operate as separate layers after the base is fixed, so the sage tends to be worth more in a shell that already has other ways to grow a creature. The body is the honest part of the bargain: at one mana it will never race on its own, and the flying is there to make the self-targeting line matter rather than to threaten anything. It is a payoff built for a spell-dense deck that wants a recurring, no-mana way to convert that volume into combat pressure, without asking you to overcommit bodies to the board.
