I finally made it to diamond rank!
For a while I was playing a healyonar deck, which while fun, has a tendency to fall behind if they get rid of all of your minions. I managed to climb to rank 7 with it but I kept losing, specially since its worst matchup is magmar and I was facing lots of them in that rank (stupid warbeasts).
So I went back to Vanar, but this time more of a wall-control type of deck. It's a very budget list, since I can't really afford many legendaries, so right now I'm not running any gravity wells, but the bonechill barriers combined with glacial elementals make for a really good board control combo, it can often make you gain control of the board after losing it, so it's really powerful.
Also, even though snowchaser seems like an aggroish card, it's ridiculously good at keeping board control by chipping away damage, but also by blocking paths of other cards and also combining it with glacial elementals, it's good.
The deck also makes for really fun games, you can often surprise the oponent with 10+ burst damage if they leave any walls up, morphing them with aspect of the moutains/drake/fox + bloodborn spell.
Anyway, I just wanted to rant a bit about that. I'm also excited about the expansion, lots of information about it shown today, including a huge change to how shadow creep works, thankfully.
I'm still having lots of fun, pretty good game.
