Restless Vinestalk

Most creature-lands are content to be a body that dodges sorcery-speed removal; this one rewrites the board math on the swing. Its attack trigger sets a creature's base power and toughness to 3/3 until end of turn, and the direction that flexibility runs is the whole strategic hinge. A 5/5 with trample already demands unfavorable blocks, and the shrink sharpens the trap: aim it at a bloated blocker and it collapses to a 3/3 the Plant tramples clean over, or hold an opposing threat to a manageable size going into combat. Because the clause reads "up to one other," it can point back at your own side too, propping a small evasive attacker up to a base 3/3 so it trades up or breaks through a would-be blocker. The catch is timing: this fires only on attack, so it shapes combat rather than answering a spell, and an opponent can respond to the trigger or simply kill the land before you declare attackers. Everything is paid at both ends. It enters tapped, so it never contributes the turn it arrives; animating it costs the full five before you can attack; and the body evaporates at end of turn. It spends most of the game as a manabase piece, becoming a threat only when there is surplus mana to burn. The green-blue pairing states the intent plainly: a land for a grinding, interaction-heavy deck that converts excess mana into a repeatable evasive clock doubling as combat control.
