Description
You need more means of exiling your cards than Ashiok alone to win with it, but it gets there

If the targeted player skips their next turn, you'll control the next turn the affected player actually takes

Interestingly enough, if Ice Cauldron gets destroyed while it has a card attached to it, you can still play that card as though it were in your hand

Basically, its a massive resource advantage that comes at no real cost to you
