I'll admit costing was a tricky one, because it's value changes during the game and is very dependent on what type of deck your opponent has (e.g. useless against pillarless!)
I first had it cheaper but then went a bit higher as to try avoid rush decks getting a lockdown very early on in the game. Too expensive though and no-one would bother using it...
In the right moment, this card can make or brake a match, in the wrong moment it does nothing at all....how to cost such a card!?!?!?
I will add a poll to let more people give their opinion and see where we end up...
Thanks for feedback
Oh, and TimerClock14, I've not often (if at all) come across aether/earth combo so maybe would not lead many to create lockdown..? maybe that's just me though, since with this it is possible, I see that.
