Some of these cards are pretty cool, but the entire expansion doesn't feel very inventive. Two xpacs in a row with no new mechanics and just variations on existing themes. I hope they aren't running out of ideas or something.
If they did these more often, that would be one thing. I can't help but compare to MTG, where there's a new set every ~3 months and always at least one new mechanic.
oh, and do we have any idea how much mana the 3/2 weapon deadly fork gives you costs? That will change the power of that card alot. If it's just 1 mana, it's OP. If it's 2, it's great. If it's 3+, it starts being 'ok'.
