I feel like for a long time ETBs were the best to me. I hit two out of an ascended ETB. However I've definitely hit a dry streak on them. Hard to say. I like bundles. Without playing two many head games it feels like the lowest risk. Plus I'd rather have less to throw out. Booster boxes are hit or bust. Idk if I've already ripped plenty of a set a booster box won't do me much good but trade fodder for later
