Fblthp, Lost on the Range

Plot exists to smooth a single turn: pay for something early, cast it later for free. This little Homunculus converts that one-shot trick into a standing engine by pointing it at your deck instead of your hand. Whatever card is about to be drawn is always visible, and whenever it is a nonland card it is eligible to be plotted at its mana cost, and once plotted it costs nothing to cast later. The effect reads like a cross between a scrying stream and a delayed-payment discount, letting you sink surplus mana into cards you have not drawn yet, then spend real turns casting the results for zero. And because plotting is a special action rather than a once-per-turn ability, a deep enough mana pool lets you plot the visible card, reveal the next, and plot that one too, chaining as far as the main-phase window allows. What keeps this from pure runaway advantage is the friction baked into plot itself: nonland cards only, and sorcery-speed timing that forbids any of it at instant speed. It front-loads the cost of cards you have not yet drawn, so no mana ever sits idle. Ward on a 1/1 is the concession that pays for the value: the body folds to any real blocker, but a stray removal spell has to clear a tax first, buying the engine another turn. The whole package rides on what you are about to draw, not the creature holding it in view.
