This deck has a solid core of aggro threats, Pheonix Chick and Bloodthirsty Advasery, that is enhanced by cards like Mechanized Warfare and Kumano Faces Kakkazan, which enhance the power of those threats
Urza not only does actual everything, from killing things to drawing cards to gaining life to making threats, but he gets to do it twice a turn, with a huge starting loyalty
For example, by taking the various sequences of seven common cards that appear in Neo Revelation booster packs, it is possible to reconstruct the 121 card commons sheet used for this set, even though no image of one is known to exist
I might spend endless hours, days, or weeks drafting Khans of Tarkir and decide that Jeskai Tempo is hands-down the best archetype
You can take a look at a variety of YouTube unboxing videos for the cards
