Give // Take

The two halves are built to be each other's setup and payoff: Give loads a creature with three +1/+1 counters, and Take cashes those counters in for cards. Fuse is what turns the pair from a fair growth-and-draw split into a self-contained engine, since casting both at once lets you stack counters and immediately liquidate them, drawing three from a single combined cast at six mana. The wrinkle is that Take cares about all +1/+1 counters on the creature, not just the ones Give placed, so any other source of +1/+1 counters (an outlast trigger, a graft donation, a modular crawler) widens the back half into a much bigger refill. Both halves are sorceries, so there is no instant-speed rescue here: Take has to be the proactive play, sacrificing a creature's accumulated growth on your own turn to convert a board investment into raw cards before that body trades or stalls. The split exposes the central tension in fuse design, which is that each half has to stand alone in its own color while the combined cast justifies stapling them together. Here the seam shows, since Give on its own is a modest pump and Take on its own does nothing without a counters board, but fused they form a closed loop of investment and return that neither color could print as a single card.
