Slumbering Trudge

The math is the whole engine: a fixed 6/6 body whose price is time, metered out in stun counters instead of mana. Pour more into X and you buy off the delay; three minus X sets the counter count, so a big X arrives clean while a cheap cast lands stunned, tapped, and asleep through your untap steps until the counters bleed away. What makes this design sharp is that it collapses two knobs (mana efficiency and battlefield readiness) into a single decision made at cast time, then locks it in. There is no rushing a stunned creature: stun counters intercept the untap event itself, so untap effects only burn off a counter rather than actually readying the creature, which means the sleep timer is genuinely durable rather than a soft speed bump. It is a payoff for the patient and a discount for the desperate, the same card wearing two different clocks depending on how much you had to spend. The green tradition of oversized bodies at aggressive rates usually pays with a drawback on combat (defender, can't block, sacrifice clauses); this one pays with pure tempo, front-loading the cost as turns you don't get to use it. And because a cheap cast enters tapped, the discount version cannot even hold the fort as a blocker while it sleeps: you are paying in defenselessness now for a 6/6 that swings later, a curve-topper you can flop out early only if you can afford to leave the board open until it wakes.
