That leaves you with 30-35 cards that will help you enact your game plan
The outlook on Counter Blitz is great because counters show up in every new set and will only increase the power here
Green/White: Artifact ETB These colours are concerned with abilities that trigger when artifacts enter the battlefield
While this will mostly be relevant in casual play, it's worth pointing out that if you have a Naban, Dean of Iteration on the battlefield, every Wizard that enters the battlefield will trigger Warstorm Surge, Fathom Mage, Angelic Chorus, and Purphoros, God of the Forge (among others) an additional time, which opens up an entirely different layer of deck-building potential that was missing with Panharmonicon, which only triggered abilities on artifacts and creatures
And I can drop some big, beefy aura to amp Zur up to kill in a few hits, and run some pillow fort stuff like Propaganda and Ghostly Prison, along with Rhystic Study, Necropotence, and well, you get it
That's what happens when you combine Tinker (which could get out the Jar almost immediately) with Megrim (so that your opponent would take 14 damage from a single Jar discard, assuming they could not play any cards in time)
