We drafted a paper version of this Cube at an R&D party recently, and I snapped up Mishra's Workshop with my first pick and never looked back
Fun Ranking: Fun (Borderline Kinda Fun) Kona, Rescue Beastie We can easily tap Kona using cards like Smugglers Copter or Ornery Tumblewagg to cheat haymakers like Portal to Phyrexia or Avenger of Zendikar into play
Legendary Creature - Human Soldier Pir, Imaginative Rascal Partner with Toothy, Imaginary Friend (When this creature enters, target player may put Toothy into their hand from their library, then shuffle.) If one or more counters would be put on a permanent your team controls, that many plus one of each of those kinds of counters are put on that permanent instead
But note that this can be removed - it's simply an enchantment card that can be interacted with, destroyable by Disenchant
Queza, Augur of Agonies often sees at least some wheels in its lists, but you could run it like a group hug commander with Howling Mine effects
Honorable Mentions While we went the more all-inclusive route, there is a list that just details what Partner pairs are the most popular
