Not sure as I haven't played the game in 20 years. TLDR though: one of the decks has an extremely consistent draw engine where you can get through most of your deck in the first 6 turns, another allows you to set up a board that is nigh-unkillable, and the other steals all of your opponent's cards then prevents them from using them.
So basically Hearthstone is turning into Yu-gi-oh?
The powercreep for that game is insane now
