Sokka, Lateral Strategist

Card advantage in white-blue has always come at the cost of a turn: you swing or you draw, and the go-wide plan and the value plan compete for the same window. This clears that tension by paying you off for the wide attack itself. The gating clause does the work: it fires only when a companion joins the swing, so it wants a board before it wants aggression, and it turns what would be a risky all-in into a repeatable draw engine. Vigilance is the piece that keeps the ask honest. It is a defensive concession, not an evasive one: Sokka still has to enter the red zone as an attacker to trigger, so he can be blocked, chumped, and killed like anything else, but after swinging he stays up to block the crackback. Committing him to combat no longer surrenders your defense. The 2/4 body matters for the same reason the trigger does. Four toughness on a three-drop shrugs off the small removal and incidental damage aimed at a token general, which is decisive for a card whose entire value proposition collapses the moment it leaves the battlefield. This is a wide-deck engine built to keep firing across exactly the board states its own strategy is trying to build.
