Soulknife Spy

The template blue card-advantage attacker, stamped out to spec. Its whole lineage runs through creatures whose text is "connect and draw": the effect is old, but the pricing here is the point. A 3/2 body is aggressive enough to trade up early and to push through a stalled board, and the draw trigger fires only on damage to a player, which rewards keeping it swinging into faces rather than parking it on defense. The design pays for its power with a plain gap: no evasion is printed on it, so the card advantage is contingent on solving the blocker problem yourself, whether through combat math, a pump spell, or an opponent who cannot profitably block a two-toughness body. Get it through once and it starts paying rent; leave it home and the trigger simply never comes online. Because the draw is stapled to combat damage rather than an activated ability, it costs nothing extra to fire, which separates it from Ophidian-style effects that ask for mana each turn; the trade-off is that it draws exactly one card per connection, no matter how hard the hit lands, capping the ceiling that a Cold-Eyed Selkie enjoys. It exists so that a color built around card selection has a body worth turning sideways: an aggressive three-drop that converts each unanswered swing into gas, with nothing to build around beyond attacking.
