Guile

Guile {3}{U}{U}{U}

Creature - Elemental Incarnation | Power/Toughness: 6 / 6
Guile can't be blocked except by three or more creatures.
If a spell or ability you control would counter a spell, instead exile that spell and you may play that card without paying its mana cost.
When Guile is put into a graveyard from anywhere, shuffle it into its owner's library.
