One of my favorite kitchen table decks from a decade-ish ago was "Isoschron Wolves" (slam Moonmist under Isochron Scepter, bully people with werewolves), and I recently pulled Kraum, Ludevic's Opus in etched foil. I've long toyed with porting the deck to EDH, and adding blue seems essential to be able to Fabricate/Tribute Mage into my Scepter and Phyrexian Metamorph to copy it. We also get some sweet cards to put under the stick, chief among them Dramatic Reversal. Here's my quick sketch of the deck.
