As a casual Standard only player, I had the damnedest time trying to beat The Amazing WTfBUr1n3duRF@C3offTurn2 Reno. Just when you think it's over, Galakrond says, "Hold my beer" and proceeds to do things that will scar you in ways that will eventually be chronicled in the Journal of Experimental Psychology.
Luckily people much smarter than me got it done with just a few Wild cards. Figured I'd pass it on.
Note: This is probably not the most optimal way (or enjoyable). This is just a way.
Make it to turn 5 with (or in Galakrond's case, at least 5 mana):
1x Test Subject
Then proceed to kill your Test Subject about 80 times....or 150+ times. #cryingontheinsdie
