Hexproof
Whenever you counter a spell or ability, you get an experience counter.
At the beggining of your upkeep, search you library for a card with converted mana X or less, where X is the number of experience counter you have, and put it into your hand.
Counter target spell or ability.
If that spell is countered this way, exile it instead of putting it into its owner's graveyard. You may cast that card without paying its mana cost for as long as it remains exiled.
