My little brother got a 36/38 using enchantments on my first game without help

It had vigilance, first strike, flight, and summoned 36 1/1 tokens every time it attacked. Also, if you somehow killed this behemoth, it came back to life one time, and untapped all his lands every time he attacked.

Needless to say, a 7 turn game lasted an hour and a half because of this...
