While Scarecrow is active, you can't be attacked by characters with A of 2 or less.
Half-Elf Bard: Apprentice Order of the Gauntlet reads
While Half-Elf Bard is active, your other character dice of equal or lower level to your highest level Half-Elf Bard are not affected by opposing character abilities.
If I have Scarecrow in my field and no other characters, and my opponent has Half-Elf Bard in theirs, can my opponent attack with his 2A characters at the same level as Bard because they ignore character ability that affect them?
Thanks!
