Fist of Jaraxxus has the interesting effect of dealing damage when it is played or discarded. Both Warhorse Trainer and Flash Heal, however, offer more standard fare; the former grants a +1 attack buff to Silver Hand Recruits and the latter heals five health for the cost of a single mana point. Living Roots gives the choice of calling forth either two 1/1 Saplings or dealing instant direct damage. The final card, Charge Hammer, changes the Shaman’s hero power to a damage dealer when his weapon is used up.
Hearthstone has got a bit more to add to its previous jousting announcement. Five new cards are joining The Grand Tournament expansion: Fist of Jaraxxus (Warlock), Warhorse Trainer (Paladin), Flash Heal (Priest), Living Roots (Druid), and Charged Hammer (Shaman).
