Prodigious Growth

Six mana to bolt +7/+7 and trample onto a single creature is the kind of pure-payload Aura that has existed in green since the game's earliest days, and the math hasn't gotten kinder to it with age. The whole gamble is concentration: you commit two cards (the Aura and the host) and a turn's worth of mana into one body, and a single instant-speed removal spell unwinds both at a profit. That fragility is the tax green pays for raw size, and it's why this style of giant Aura keeps getting reprinted but rarely keeps a competitive slot: the floor is a two-for-one against you. What it does answer is the matchup where nobody is holding removal, where a creature that already connects (a deathtoucher, an evasive flyer, anything with lifelink or an on-damage trigger) suddenly closes the game two turns early. The trample rider matters more than the +7/+7 looks: it converts the buff from "your blocker is now embarrassingly large" into "your attacker now punches through whatever they chump it with." This is overkill by design, a finisher for decks that have already decided the board is theirs and want to skip to the end, not a tool for fighting over the board itself.
