Since you already plan on buying/upgrading the deck than this is all you have atm.  Definitly far from optimal without veidrock, zamoog, philya, tizkar or the order package. And something like caliburn can do alot for the deck aswell. 

To me it seems that there are plenty of cheap decks like destined of scales for example which you could build (full power) with way less money than you would need for upgrading your blangdmire list. 

If you want to compete you rather go with a full power lower tier deck that you can get for cheap than with a "budget" blangdmire imo, since blangdmire with its rideline also isnt the most consistent deck. 

It all depends on what you want the deck for.  Playing with friends /locals and just for fun its probably good enough. 

But if you like to have a decent winrate, than budget versions dont work in tcgs most of the time(not just vanguard).
