Choking Vines

The casting restriction is the entire card: it can be cast only after attackers are committed but before damage resolves, which turns blocking into something the green player gets to do retroactively. It assigns blocks the defending creatures never made and staples a point of damage onto each ambushed attacker. The parenthetical that it works on creatures that can't be blocked is the sharper trick: an evasive attacker assumes its path past your board is locked in once it has charged, and this rewrites that assumption at the last legal moment, marking it blocked and pinging it for one. The X structure scales the ambush across a whole attacking team, so a wide swing into open green mana becomes a guessing game for the attacker rather than a free hit. The friction is intentional: a one-step casting window means the card is dead in hand on every turn but the one it's built for, and the single point of damage rarely finishes anything by itself. This is combat tech from a period when instants leaned on timing puzzles rather than raw stats, and the rules text reads like a designer working out in longhand exactly how to let blocking happen after the fact without breaking the turn structure.
