Shaman decks are always being tweeked a little and this Tyler Top 5 Legend Aggro Shaman Sep 16 is obviously working really well right now as I saw him playing it on his stream with a pretty decent win rate.
Shaman decks seem to be adding more and more midrange cards to deal with a lot of the control decks on ladder. This means you can beat them in the mirror with this faster deck. Lava Burst closes out most games with a Doomhammer also bouncing off face. There isn’t much heal on the current META decks, the main problem still remains Yogg!”
