Hearthpwn

This tier list assumes a single card vacuum, but with the rock paper scissors style of weakness things get a bit more complicated. For example this list has Tavish Stormpike as a C tier but he is an MVP in my pvp team. Almost everyone uses casters, and often a majority since they have access to a lot of AOE. So his traps trigger almost every turn, with flame trap dealing double damage to casters.

Also Varden Dawngrasp as a B tier? That's at least an A. AOE damage and AOE slow is massive in pvp.
