One of the most common questions posted by new players on this forum is how to get UR rich quick.
The reality of most games is that in order to get rich quick... you can simply spend real money and buy all the packs you need until you are content with your collection. Easy enough.
The reality for a lot of players is they do not have to funds to be spending a lot (or any money) on a game. No worries though, the gap between people who spend lots of money vs those who spend very little is big only when it comes to UR wealth, but when it comes to gameplay the difference is more than manageable
To give you an idea of how much credits the "veteran" credit using players are using in order to maintain their collection I'll share my personal experience. I am currently at 98% of the collection. The 2% is always the newest cards (12-15 of them) that i dont buy until they are much cheaper. I invest in a few cheaper cards here and there, but for the most part i earn clintz from packs and playing ELO/DT in weeks i am active. And i am able to maintain 98% using anywhere from 60-100 credits every 2 weeks.
If you do are an active player and can afford to buy credits once in a while, then eventually you will see your collection grow, allowing you to play competitively in every format and nearly all events.
However, if you are an active player buy have no funds then you may want some tips on how to earn clintz and credits as fast as possible
Tips will be listed below
