Ascendant Spirit

A one-drop that agrees to be a bad card early in exchange for being an unanswered win condition late. The whole structure is a mana sink priced in snow: each activation gates on the one before it, so the 1/1 has to survive to two mana of snow before it grows a spine, then three before it flies, then four before it starts refilling your hand every combat. That escalation is the balancing act. You cannot skip a rung, and every point of snow mana you spend on the Spirit is mana you are not spending on the game happening around it, which is the price for a threat that scales past every removal-cheap answer and into inevitability. The counter it eventually gains is worth noting: because it puts a flying counter on itself at the third tier and +1/+1 counters at the fourth, an anthem-strip or base-power reset does not fully undo the investment. Snow mana as a resource ties the whole thing together; without a snow-heavy manabase the ability line is stranded text, which is the constraint that keeps a repeatable, card-drawing 6/6 flier honest at one mana. It belongs to a small tradition of one-cost creatures that trade immediate stats for a ceiling nothing else at the cost can reach, and it earns that ceiling by making you pay for the climb one rung at a time.
