One of the things that most people missed by either relying only on the MS Word version of the World of Warcraft TCG official rulebook or by glossing over the pdf version is all the cards and the abilities spoiled within. One in particular is the Instant Ally. If you don't know what I'm talking about check out Tristan Rapidstrike.
What kind of impact will cards like Tristan Rapidstrike have on gameplay?
In addition, what abilities other than Protector could you see being featured on a Instant Ally?
