It's that time again for a new Hearthstone expansion and this next one looks like a lot of fun and it's called The Boomsday Project. Doctor Boom is an old Hearthstone Legendary card that was one of the most overpowered in the game before he was rotated to wild. He's back and in his own expansion that looks like it fuses explosions with Hearthstone SCIENCE! Speaking of fuses a new mechanic MAGNETIC is for Mech cards allowing MAGNETIC cards to fuse to other mechs giving them the stats and abilities of the MAGNETIC card. It's a lot like Deathstalker Rexxar's Build a Beast ability but for mechs which looks to be very interesting.

A side note... the Hearthstone team is getting really great at making very fun videos showing off expansions and this one is the most entertaining to date. I'd recommend checking it out just for fun even if you don't plan on playing the game.
