Sword of Forge and Frontier

The acceleration entry in the Sword cycle that began with Sword of Fire and Ice, and the one built to keep an aggressive deck's engine running rather than to break a stalled board. Every Sword pairs a +2/+2 buff with protection from two colors and a combat-damage trigger, and the axis each one lives on is set by which colors it dodges and what the hit does. This one ducks red and green (the colors of removal-heavy aggro and stompy ramp) and converts a connection into a burst of impulse card advantage plus a second land drop, so the trigger reads less like value and more like an accelerant: the attacker that got through is expected to keep getting through, and the extra land keeps your curve ahead of the resources you are spending. The impulse wording is where the timing lives. The exiled cards are playable only this turn, which pushes the reward toward decks that can empty a hand fast rather than bank cards for later, and the bonus land drop rewards a deck already holding the lands to sink into it. Where Sword of Fire and Ice reads as the tempo Sword and Sword of Feast and Famine as the disruption one, this is the tempo-into-more-tempo model, and its ceiling scales with how quickly a protected attacker can be turned into repeated damage before each turn's impulse window closes.
