Da Vincis Designs $50 Super unique look, good cards with no other special versions, I like where this is going
The best colors for this kind of deck are probably Mardu or WUBR, as it gives you access to Smothering Tithe and Wheels, Prying Blade, Treasure Map, Brasss Bounty, and ways to make tokens
What interactions and abilities did I miss
It is very hard to beat tokens going wide as a midrange deck without some sort of mass removal but you don't want to be playing Wraths and lots of your own creatures
Tataru Taru is a reasonable mana generator in mono-white which is still the color that struggles the most with getting those more explosive turns where mana can be leveraged for big plays
You can get several other, better, misprints for that amount of money, and those cards have a much greater chance of appreciating in the future
