Rise of the Hobgoblins

Hybrid mana does the heavy lifting here in a way the two-mana rate disguises: both the enchantment and its first-strike ability can be paid for by a mono-red deck, a mono-white deck, or anything between, which makes it an anthem-style payoff that asks nothing of your manabase to function. The X-cost token burst is the part that scales. Cast for the minimum two mana and you get an enchantment that does nothing on entry but waits to pump; commit more mana the turn it lands, or hold it for the late game when converts a surplus into a board of Goblin Soldiers in a single card. The tokens being both red and white is not flavor decoration: it lines them up exactly with the activated ability, which grants first strike to precisely the colors of creatures you just made. A wide board of 1/1s that all strike first becomes a combat-math problem for any opponent without reach or evasion, since each token trades up or blocks above its weight. The design sits at the seam between go-wide token strategies and the kind of single-color aggro deck that wants its payoffs castable off a single basic land type. It folds a token producer and a first-strike granter into one permanent, and the hybrid cost is what lets it slot into far more shells than its printed colors would suggest.
