As a draw engine, Tom, Bert, and William is fantastic. However, this commander really shines as a discard enabler. Rather than focusing on sacrificing big creatures for cards (which this deck can also do through anticausal vestige, and daemogoth titan), my build focuses on sac'ing little creatures (i.e. bitterbloom bearer faeries, pests) to enable madness shenanigans (shadowgrange archfiend, emrakul, necrogoyf, etc). This is supported with a witherbloom lifegain/aristocrats shell and a few ways to pump for maximum card draw in dire situations like berserk. Be careful not to bicker too long with your playgroup before you turn to stone because Tom, Bert, and William will get to your opponents's hands and life totals quicker than they snatched up Bilbo!
