Congratulations! Legendary mode is pretty hard, and I balanced the expansion missions to require near-perfect play in order to succeed. So don't get discouraged. =)

Keep in mind it's not that he Gardener's can't be attacked by adjacent units (they can, normally.) It's that Runners can't attack adjacent units, and all the enemy units/statues on that map are Runners.

If you're not already, make sure you check out each units and its abilities to know the limitations of your enemies and how to exploit their weaknesses and avoid their strengths. =)
