This is the Chakki NA Summer Prelims Aggro Shaman Deck he brought to the HCT matches.
The interesting tech here is the 1 x Earth Shock. This isn’t commonly seen in Aggro Shaman, but it’s a 1 mana card that allows you to keep pushing damage to face through a taunt.
There is also a lightning Storm, another tech that’s been creeping into more and more aggro Shaman decks. SMOrc’ing the face isn’t as easy as it used to be, board clears and silence is being teched in to keep the damage going face.
