I've finished the Gargoyle today! It's the seconds common light tower you've voted for. I've put both jhoijhoi and shimakura as authors, as shimakura's Force Apprentice was the same idea but different lore. Here's the artwork!
Card and in game
And here's how the card looks. I think you can decorate a beautiful garden with those gargoyles! The numbers are not final yet. That being said, I'm currently working on a mechanism to prevent abilities like stun, warp and the new knockback to not become totally inbalanced in the endgame.
