You can make a lethal alpha attack, you can force an opponent into bad attacks and blocks, and its just one of the most interesting cards in Boros, especially in Commander games with full boards
Now, granted, Orcs dont have nearly as much support as Goblins, Zombies, Elves and other creature types, but a Sauron Orc deck sounds perfect flavor-wise
Skybridge Towers A Sphere land card from the Phyrexia: All Will Be One set
One attack can accelerate your mana, deal damage, and steal value from the opponents deck all at once
Im surprised that this doesnt see more play
Thoughtseize is certainly a reasonable enabler and if we get another incidental discard effect thats playable on its own this could make it into FNMs
