Vraska, Betrayal's Sting is a flexible proliferate option that also acts as removal or a finisher, but personally I feel she's a bit overcosted at 5 mana minimum
With the preponderance of good, cheap mana rocks and other options printed over time, the Hart has lost a little of its play share
Rather than losing just a part of the top like the Elementalist above, there have been cases where the card is simply demolished by the booster gods, giving a deep crimp on two separate halves of the card before it is sliced and the pieces are sealed into different boosters
Have you researched the value online
Weve seen the Blizzara mode in just about every set for the past few years, and its pretty much always a solid removal spell for blue decks
Two sorta implies youre expecting every game to end early, since even if you can use the discard-draw mode in a pinch you really dont want to, and already I expect a lot of Lesson packages to be two copies of the generic one you want to find and one flex slot
