Ok, in this case... willful ignorance.
The new Magic Online set released today, "Dissension". Since I wanted to play with the new cards, I bought one of their preconstructed decks. Now, usually when this happens I research all the various decks so that I can choose one that has the best value, or that I'll enjoy the most. This time, I tried a different experiment -- I specifically avoided any knowledge of the cards in the decks.
As it turns out, the experiment was a wild success! I had a lot of fun not only seeing the new cards for the first time but constantly being surprised by what was in my deck. It's a great way to see some of the new content in the latest set with an interesting twist.
Lack of knowledge is a fun thing for me, I guess. I like being surprised and dealing on the fly. Perhaps that is why I always such an advocate of what we called "manly random" in AOM development -- random map, random civ, random team composition.
It's too bad that there isn't a "make a random deck" option in MTGO. Hm, it wouldn't take much work to write a program to generate random deck files that could be blindly (to me) read by the game...
