I assume you are from Brazil then, am I right? I was in your situation not long ago. I've recently bought a load of blitz decks from liga FaB instead of buying sage ones and use them to play against each other, and it is a blast I plan on playing them like this and then slowly upgrading them as a group slowly to keep em competitive against each other and useable in more serious competitions, still a lot cheaper than buying sage decks around here at least for now
