[Autumn]

Ice Skate is pretty strong, I use it quite a lot, I use it very sparsely given I don't like to overly abuse these things but Ice Skate can be used in conjunction with tons of ice to traverse great distances very often, so often infact that you can use it to kite someone around every single turn, never allowing them to touch you as you have full control over the battlefield

It is not an infalliable strategy but it is one I am surprised hasn't been diminished quite yet, as I've seen it done a few times in the past in conjunction with Snow Crow. I would suggest that Ice Skate gains a cooldown, nothing fancy or special, given it's immense potential travel distance, 5 turns seems like plenty of time to catch up and punish the verglas for a bit.
