5 rulings from Wizards of the Coast
- 4 October 2004Choking Vines will make any creatures it targets become blocked, even if the creature had blocking restrictions on it. For example, you can make a creature with Islandwalk become blocked even if the defending player has Islands. This is because evasion abilities only prevent creatures from being assigned to block them.
- 4 October 2004You can declare zero targets, with X=0.
- 1 April 2008Choking Vines isn’t particularly effective against creatures with trample. Since the creature with trample has no blocker to assign damage to, all the damage will be assigned to the defending player.
- 1 April 2008If a previously unblocked creature becomes blocked as a result of Choking Vines, any “When this creature becomes blocked” abilities that creature has will trigger. Any “When this creature becomes blocked by a creature” abilities that creature has won’t trigger.
- 1 April 2008You may target a blocked creature with Choking Vines. Choking Vines will deal 1 damage to it, and have no other effect on it.
