When Urza, Lord High Artificer enters the battlefield, create a 0/0 colorless Construct artifact creature token with "This creature gets +1/+1 for each artifact you control."
Tap an untapped artifact you control: Add U.
5: Shuffle your library, then exile the top card. Until end of turn, you may play that card without paying its mana cost.

Quote from ShankmasterShank »Really pre-mending walkers are all too powerful to make cards for, as they are basically shapeshifting gods, and yet we have Windgrace and Freylise, both of which are on level with Urza.
