Well, this isn't a card suggestion, but rather a suggestion about cards.
To the point, many people think Pulverizer is overpowered, costing just 4+1perability to remove a permanent. To rebalance this, they suggest a simple way - upping the cost. However, I have a different idea.
After a Pulverizer Shatters, it is put into stasis until the end of next turn. Simple, working, and hampers the thing a bit.
This could also be applied to other cards that need rebalancing, like Otyugh, Hourglass or whatever.
So, what do you think?
