I actually had my first "successful" friend add... I only toss out friend invites if I want to compliment good play or ask questions and, until today, all have been refused.
The guy was pretty cool, he just started a few weeks ago but was playing the full wallet warrior deck (Grommash, Alex, Rag, Geddon) and I was playing Ramp Druid. It was an extremely close match but in the end he just couldn't get through my taunt wall. The reason I added him to my friends list was because he was running a few taunts (the sludge guy who goes explodey) and a Sen'Jin and I never saw an Execute so I was curious if he swapped those out in favor of the taunts. Turns out he was running the, standard, 2 executes but they were buried at the bottom of his deck (we were both less than 10 cards left at the end so he got really unlucky there). It was actually an enjoyable match because it was one of the very few that, legitimately, could have gone either way depending on a couple key card draws.
