My question that I ask to all of you is: What cards should I push to acquire that will be quality cards and be versatile enough that I can use them in a number of decks?
Hy Stephen. Well, the choice is quite simple.
First, i suggest you to acquire the restricted cards for T1. 95% of those cards are used in a lot of T1 decks.
Then, i think that you've to make a choice. If you're Powered, just buy the card for the deck that you want to play.
If you're unpowered, i think that the best choice for the moment for you is to buy cards for decks like MonoRed, MBC, LLL, GayFish or something like those.
Those decks are not expensive and are good for play.
