Assault // Battery

The split-card chassis usually divides labor across the color pie, offering two different effects you might want in two different situations. This one divides along the curve instead, and that is the cleverer use of the format. The red half, Assault, is one-mana point removal that picks off a small early creature or pushes the last two damage through a low-toughness blocker. The green half, Battery, drops a 3/3 Elephant for four mana, a body that holds the ground the turn it lands and starts trading the turn after. Neither half is remarkable on its own: two damage and a vanilla 3/3 are ordinary rates by any era's standard. The value is structural, in never holding a dead card. When you are behind on tempo the burn is live; when nothing on the board is worth shooting, the Elephant is still a turn of board presence. What makes the cost-split version cleaner than a situational modal is that the mana lines up with the timing: the cheap half wants to be cast early, when you are short on lands, and the expensive half wants to be cast late, when you have them to spare. You almost always have the mana to cast the half the game is asking for, because the game tends to ask for the cheap half exactly when mana is scarce.
