Hexis

If a spell would be countered, it costs at least it's converted casting cost to counter.
If a spell would be put onto the battlefield, it costs at least it's converted casting cost to do so. If the spell has no casting cost, it's average of power and toughness, rounded up, is converted to a casting cost instead.
For when one thing makes and another is made, there is between them an act of making.
-Aristotle, Nichomachean Ethics
