Slimjim being Slimjim (his main account name is fuzzy now), so was not gonna reply, but wrong math has to be pointed out. No, chance to draw certain legendary by turn 4, 5 is not 1/30. Only simpleton calculates like that. Not gonna do the calculation now, but it should be close to 40% (or high 30% range). edit: forgot it was warlock. with Life Tap, it’s easily around 45% chance to draw Skull when full mulligan-ed
Stay in school, kids. There is a reason why grown-ups say that (you don’t get used, or in this case, feel cheated when there is none).
