Therein lies the problem. The two formats i'm most interested in playing in are Modern and Legacy, and in both, the entry costs are pretty steep. I do like Standard, but not nearly as much as i like eternal formats. To get back in the game, coming from a point where you have no cards at all, i'd have to buy-in at a pretty steep cost. Even a pretty inexpensive legacy deck would set me back a pretty penny, at least a couple hundred dollars (remembering the dollar is 3,50 Reais), and a modern one at least as much, and then i'd have to drop about another couple hundred dollars each month for a few months buying boosters, fat packs and getting my feet wet in FNM's.
Sure, once i reestablished myself with a sizeable amount of cards to trade & resell, i could estabilize and not need to keep dropping in cash every month just to keep up.
The entry barrier is what's stopping me. I mean, sure, i don't need to go all-in like that, and i can just play drafts at FNM's until i manage to get a few cards, but even that cost is pretty steep to me as it is. Once i get a stable job with disposable income, i can see myself getting back into it, but as it stands... Too expensive, and i can get at least a little bit of the fun by playing online through Workstation or Cockatrice.
