Shape of the Wiitigo
Six counters arrive for free, and then the maintenance bill comes due. The upkeep clause is the entire wager: the enchanted creature has to have attacked or blocked since your last upkeep, or it sheds a counter instead of gaining one. That phrasing matters. Blocking counts, so a creature parked on defense can still feed the engine the turn an opponent swings into it. What the Aura actually punishes is inertia: a board where nobody attacks and your creature has no one to block. In that stall, the counters drain off one upkeep at a time and the investment quietly unwinds. So the card does not strictly demand aggression; it demands that your creature stay involved in combat on either side of it, which is a subtler constraint than "keep swinging." It also sharpens the classic Aura risk: removal answers the creature and takes all six counters with it, but even leaving it alive, a turn where your creature neither attacks nor blocks starves the trigger without spending a card. The upkeep counter that vanishes on a passive turn is the price, and you pay it in tempo whenever the table goes still. That strange axis (a six-mana investment that rewards an active board and erodes against a quiet one) is what makes this a flavor-driven curiosity rather than a green workhorse: the math of the build is sound, but it asks the table to keep swinging, which is the one thing you cannot guarantee.
