Sprouting Renewal
Green's answer to artifacts and enchantments has always suffered from the dead-draw problem: against an opponent who never presents a target, the card is a blank you wish you had cut. The design here defuses that from both ends. When there is nothing worth destroying, the spell instead builds a 2/2 with vigilance, a defender that keeps blocking duty even after it swings; when a threat appears, the destruction mode is waiting. Neither half is stranded. Convoke is what stitches the two together into something more than a modal Naturalize with an escape hatch. Because tapped creatures pay for either a generic symbol or a symbol matching their own color, a green creature can cover the while others cover the
: a wide board can push either mode toward free, so the removal lands without draining your development and the token mode rebuilds the very board you tapped out to cast it. The tension is that you choose one mode as the spell goes on the stack, so this is not open-ended flexibility held in reserve; it is a hedge resolved at cast time. Green pays for stapling two effects to one card by giving up the option to hold both open, and that trade is what earns the slot. The payoff: green's most conditional utility card, the answer you never wanted to draw when it was blank, always has a job the moment it leaves your hand.
