Bedlam Reveler needs to be linked in Which Colors Should I Play under red.

In the same section you could mention that white is typically very strong at sideboarding against all kinds of matchups, e.g. Stony Silence, Rest in Peace, Kor Firewalker, Timely Reinforcements, Rule of Law, Aven Mindcensor, Worship. In my eyes, red ranges second at strong sideboard cards, with Blood Moon, Anger of the Gods, Pyroclasm, Shatterstorm, Ancient Grudge, Crumble to Dust, Sudden Shock, Rending Volley.

Couple of things:

1. I love this primer. Having played for years now and getting higher rankings in tournaments and even getting into the Top 8 of of SCG IQ, I have a pretty large understanding of the game. However, when I first started, it was really rough and had to teach myself. This primer would have been invaluable and would have smoothed the learning process tremendously. I hope that this primer has helped people getting into the format, I've even shown this primer to people trying to get into Modern. So great job!

2. The maindeck I run is B/W Tokens, and for accuracy sake, Bitterblossom is seen more often than Brimaz or Hero. Usually they are found in the Raise the Alarm shell. I think including Bitterblossom in the description is necessary because it usually sees more play than the Raise the Alarm version.

The goblins area looks good, however you should probably mention Burning-Tree Emissary - it makes the deck much much better, also another black splash card that gets played a lot is Earwig Squad.

Uhh... Angel's Grace lets your life total go negative? (In the Ad Nauseum deck section)

Hmmm, that's probably supposed to be Phyrexian Unlife.

Nope, never mind, it's the same clause. It's because if you make yourself lose life as opposed to take damage, then the life loss won't be reduced to 0 because they're two different wordings. Only damage will bring you to one, but a loss of life can bring you negative without loosing.
