I was winning at a good clip with some old standby decks I like to use (mitosis devs, disco-hole, grab-bow, pandebonium, etc.) then got a bit bored and started experimenting. After a good series of losses, I tried going back to a sure winner only to get a serious case of quanta-lock. Then I couldn't break out of the funk, didn't matter if it was PvP or arena, I was getting quanta lock game after game. Other times, like using mono-aether against key FG's, I had the situation where I'm dead before I draw my first phase shield.
The pseudo rands hate me right now!!!!
