Soldier of the Grey Host

The pairing of flash and a combat pump is the entire design logic: an ambush blocker that doesn't just trade, it rewrites a losing block into a winning one. Held up during an opponent's attack, it drops in as a surprise flyer and hands another blocker +2/+0, so a modest ground creature suddenly eats an attacker that expected to connect. The pump targets any creature, which is the quiet flexibility: it can land on the Spirit itself to win air combat, on a chump blocker to make the block lethal, or on one of your own attackers to push extra damage through. The tension it resolves runs the other way, though. Four mana held open through a combat step is a real commitment, and the +2/+0 lasts only a single turn, so playing it out early forfeits everything the card is for. This reads as white's take on the reactive combat piece, a color that usually buys ambush value with restrictions rather than raw stats. The flying body keeps the mana from being wasted even when the pump is marginal: a flash flyer is still a defensible blocker or an evasive threat on its own. A role-player built for the deck that wants to represent open mana and win the combat math, not a card that takes over a board by itself.
