I solid strategy but requires a lot of DEC. I prefer to own cards, while you don't get powerhouse cards like the ones mentioned above you can beef up some common and rare cards that allow you to compete at solid win rate. Now I will admit for newer players, who haven't had the chance to buy lots of commons when they were going for .02 and .03 cents USD, this is a good opportunity for newer players.
