Second Harvest

Most doubling effects attach to a resource and amplify at the moment of creation: Doubling Season and Parallel Lives both work on tokens as they're made, front-loading the multiplication before you know how wide the board will get. This one takes the opposite approach. It photographs a board and mirrors it, copying what you already control rather than boosting what you're about to make, so the math is multiplicative and immediate: three tokens become six, six become twelve, and it draws no distinction between 1/1 Saprolings, Treasure, Clues, or copies of a copy made earlier in the same turn. The instant speed is where the leverage lives. Held until attackers and blockers are committed, the doubled army arrives after the combat math is already locked in; passed to an opponent and cast while they think the turn is theirs, a token engine that read as a slow grind resolves into a lethal swing with no warning. The deckbuilding tension it creates is honest: it's dead on an empty board and merely fine on a small one, paying out strictly in proportion to work already done. That payoff curve, flat early and exponential late, is why it plays nothing like the static enchantments that double tokens passively. Those want you to set up and forget; this one rewards patience, then converts an entire board at once the instant it's widest.
