Darkmoon Card: Vengeance

Source
Collect the Furies cards (ace and 2-8) to assemble a Furies Deck which you can turn in to the Darkmoon Faire for the Vengeance card.

Adding reflective damage on being attacked and having the considerable amount of +51 stamina, this card is obviously meant for main tanks. The best use is for a Protection paladin; the Holy damage threat is even more valuable when combined with Righteous Fury. Although the proc rate is low, the +51 stamina alone makes this card worthwhile.
