It's really awesome, especially the vine, which makes the game more challenging!
Thank you!

Vines will be destroyed by damage on the tile, so even if you can't kill the psion on turn 1, you can still attack it to destroy the vines underneath it. It is explained in the tooltip if you hover the tile.Particularly because it felt like, unless you can kill a Psion with damage on turn 1, you can't ever get rid of the vines
