The cards posted above are the only copies of the cards in existence with Robert Schusters name on them
Part of a cycle that features the almost-as-broken Gaea's Cradle and somehow the hilariously unbroken Shivan Gorge, Tolarian Academy taps to make a mana for each artifact you control, which led to decks that would dump their entire hand of cheap artifacts, make a ton of mana by tapping and maybe untapping Tolarian Academy, and then use big card-draw spells like Windfall and Stroke of Genius to refill before eventually milling the opponent out with Stroke of Genius, potentially all on Turn 1
Usually, this two-mana creature goes into decks where most of the cards dont cost that much mana, and where the benefit of having an extra card each turn outweighs the downside of losing life
For long-time Magic players, this functions in a similar way to Living Weapon or the more recent For Mirrodin! mechanics
The mythics of Hour of Devastation are horrible from a value perspective, with an average value of just $4.52
