Sedge Troll

A red creature that wants you to play black mana: the original color-pair handshake, printed before the color pie had language for what it was doing. The Swamp clause is a hybrid incentive a decade before hybrid mana existed, and the regenerate cost commits the rest of the way, asking a red deck to keep at least one black source online through combat. In design history, this is the moment Magic discovered that a creature's worth could be a contract with the mana base rather than a label on the card frame: pay the two-color tax and you get a body that grows and survives removal for a single black, well above the curve for the era. The card also stands as early proof that regeneration was the load-bearing keyword of the original troll designs, the mechanic that justified the modest printed stats. Most of the tools later red-black builds use to ask for a splash (drain triggers, sacrifice payoffs, recursion engines) trace their logic back to this kind of conditional rate. It belongs to a simpler design vocabulary, but it preserves the first idea intact: that the mana you choose to run should change what your creatures are worth.
