Excerpt from: The 10 Greatest Boogeymen from MTG History by Brian Demars

Dentophobia (Fear of Teeth), 2002

The release of Odyssey had a profound effect on how Magic was played thanks to a fairly unassuming basketball-headed, heavily-toothed, psychopathic Atog.
By Atog standards, Psychatog was an A+ Tog. Most of the hype from Odyssey surrounded Jon Finkel’s Invitational design, Shadowmage Infiltrator, which quickly took a backseat to the real menace of the format.
For the span of a few years, Psychatog basically took over the game in a way I’ve rarely seen duplicated. The card basically became the dominant strategy in every format.

In Type 1 Grow-A-Tog was the best deck by a million miles. I don’t actually known anybody who really played Type 1.5, but I assume Psychatog + Mana Drain + Gush was unbeatable.
Psychatog was one of the best decks in Extended, where it had access to Mox Diamond, Gush and Armageddon. In Standard, Psychatog was one of the most dominant decks I’ve ever seen.

Step 1: Cunning Wish / Mana Short
Step 2: Upheaval
Step 3: Psychatog
Step 4: Island
Step 5: Circular Logic

GG.
Psychatog was the toothy face of control and combo control for years. It was even a piece of the original Extended Dredge deck.
