Dauthi Mercenary

The activated ability is what sets this Dauthi apart from the cycle's plainer bodies. Most of Tempest's shadow-soldiers were stat-sticks that traded on evasion alone; this one folds in a repeatable pump, so a spare buys a point of power that the controller knows will land. Shadow gives it narrow evasion (nothing outside its own narrow combat sphere can block it), and the activation turns that connection into a variable threat: pour two or three pumps in and a single 2/1 represents four or five damage in a turn. The toughness never moves, and that fixed 1 is the constraint the whole card hangs on. It punches through every turn, but it folds to the first removal spell anyone bothers to aim at it, so it is a glass cannon by construction rather than by accident. That pairing is the entire pitch: evasion to make the damage certain, a mana sink to make it scale, and a fragile frame that forces the controller to win the race before the body dies. Note that the pump runs at two mana a point rather than the one-for-one a true Shade gives you, so the scaling is deliberately taxed; this is a creature that wants to be the only attacker doing work and asks you to convert your surplus into one large connection, knowing each point bought is a point the blocker can never answer in combat.
