This was an interesting mirror match. Whichever Unicorn came out on top would see them match victor... but ultimately it was decided by the Mushroom Seer & Thorns.

In the end, I eked out the victory due to the 2 units with 2 Magic Atk and the Thorns applying 2 extra dmg each turn.
Thanks for checking it out!
