Turntimber Symbiosis // Turntimber, Serpentine Wood

A seven-mana creature-cheat that digs seven deep and slams a hit onto the battlefield for free would ordinarily be a coin-flip you can't afford: brilliant on turn seven, a bricked hand if you draw it early. The back half solves that. Because the card can always be played as a green source (paying three life to have it enter untapped, or eating the tapped clause when the life total won't allow it), the sorcery mode is free to be greedy without ever occupying a slot better spent on a real spell. Structural insurance is what lets the front half swing for the fences, and swing it does. The +1/+1 counter clause inverts the usual reanimator payoff: instead of rewarding you for hauling out something enormous, it inflates the cheap end, so a mana-value-three body arrives with three extra counters, a genuine threat rather than a whiff. That asymmetry (fatties come down as printed, small creatures come down bulked up) dictates what deck wants this: not a top-heavy pile of finishers, but a green midrange shell where any creature off the top can justify the seven mana. The randomized bottoming keeps it honest as a payoff rather than a tutor; you take what the top seven offers, no more. Payoff and land in one card, the design trick that earns a seven-drop a home in decks that would never sleeve a straight seven-drop.
