- 1 May 2012Whether Flowering Lumberknot is paired is checked only when attackers or blockers are declared. After that point, Flowering Lumberknot becoming unpaired won’t cause it to stop attacking or blocking.
- 1 May 2012If the creature Flowering Lumberknot is paired with loses soulbond, Flowering Lumberknot will remain paired but won’t be able to attack or block.
