(with purchase of any booster box) The sky isn't the limit
Minas Tirith can ETB untapped sometimes, and then taps with two to draw if you attacked with two or more dorks - easily done here
One of the things that has remained constant is the design on the back of Magic: The Gathering cards for obvious reasons, namely that you need to ensure that no matter what set a Magic card is from, it should be completely indistinguishable from any other card in a deck
Here, the requirements to combo off include milling Pili-Pala or Basalt Monolith (to give Trazyn a self-untap ability) plus any artifact which can tap to produce more than three mana at a time, producing a profitable mana loop
Apart from lands, ramp, draw, and removal, I would make the other categories "enablers" for cards like Awakening Zone and "payoffs" for cards like Dictate of Erebos You might notice you're not running too many ways to generate enough tokens and a tad too many sac outlets or payoffs that aren't triggering often enough
