dout.net/mtg-questions/must-be-blocked-if-able-effect-makes-other-attacking-creatures-essentially-unblockable/ When you Declare Blockers, you choose an arrangement for your blockers, then check to see if there are any restrictions or requirements. If any restrictions are violated, the block is illegal. (For example, trying to block with Sightless Ghoul) If any requirements are violated, the least possible number of requirements must be violated, otherwise the block is illegal. (For example, your opponent control two creatures that he has cast Deadly Allure on, but you control only one creature. Blocking either one will violate a requirement, "This creature must be blocked this turn if able", but it will also violate the least possible number of requirements, thus it is legal.) If the block is illegal, the game state backs up and you declare blockers again. (Note that while you can, in some cases, circumvent requirements such as "This creature must be blocked" or "This creature must block any attacking creature" you can never circumvent restrictions: "This creature can't block" or "Only one creature may block this turn.") Because you declare ALL your blockers at once, THEN check for restrictions/requirements, you may block Deadly Allure'd creatures with only one creature, if you choose. This still works with Lure: This card sets up a requirement that ALL creatures must block it if able. Any block that violates more than the minimum number of requirements is still illegal. @author LevelX2
