Getting into type I: Purchasing power?

[Colossus]

I already have my own plan for my order of purchasing power, but I'm sure that there are other people out there who don't, and was wondering if anyone could give some good advice on the order that "power" cards should be purchased?

My own plan looks something like this:
1. Finish my playset of Workshops
2. 2 moxes (most likely Sapphire and Jet)
3. Time walk
4. Two more moxes (Ruby and Emerald)
5. playset of mana drains
6. Library
7. Mox Pearl
8. Playset of Bazaars
9. Timetwister.

I have two workshops already and stumbled across a cheap ancestral, but that's what I plan on getting next.  I'd ppreciate advice on the matter, since power is necessary for most type I decks, and anyone looking to get in needs to have at least a strategy on it (what is most neccessary, what can wait, and how to deal with other people who have more power than you in their decks.)

I hate to say it but things like playsets of bazaars and workshops are risky especially the shop.  It is a matter of personal opinion but those two cards have the potential to get restricted(mainly the shop).  I would put a playset of drains over the shops since the workshop can be gotten easily and cheap if you are patient.  I do like the rest of the list but can't decide if I would go for the time walk before or after the moxes.  

P.S. Dont nag on me about the shops and bazaars because it is an opinion
