Karn Liberated (2/8)

Karn Liberated is extremely powerful, thanks to a confluence of numbers and abilities that make him a real nightmare to stare down. His mana cost is actually perfect; with all three of the "Urzatron" (Urza's Tower, Urza's Mine, and Urza's Power Plant) lands out, you can put him out on turn 3, since they conveniently produce 7 mana. His -3 annihilates a permanent (like a land), and his +4 lets you rip your opponent's hand apart (non-selectively, but it's still good). His ultimate is pretty crazy (restart the game!), but it's unlikely you'll need to use it or be occasioned to do so; if you do, though, it's not too hard to make sure you win the restarted game quickly, since you're starting with a plethora of things. The times you'd want to restart the game, though, are not times you're likely to have a Karn at 14 loyalty.

Even without his ultimate, Karn is crazy good. His mana cost is ideal, he has all the support he needs to wreak havoc, and he even protects himself rather nicely. Decks in Modern (and, to a lesser degree, Legacy) need to be able to respond to the Tron gameplan of powering out an early Karn (or other large fatty), lest they get reamed.
