Want to crush your enemies and drink their tears? Want to watch the light drain from your opponent's eyes? Want to go to time every round?
Look no further.
62 Doom Blade is exactly what it says; a 62-card deck with effectively nothing but Doom Blade variants.
How do you play this deck?
It's quite simple; they play a creature, you kill it. Repeat as necessary.
Okay, but what if they don't play creatures?
You're screwed, at least until the sideboard comes in. Simply take out your bad removal spells and put in your good anti-spell cards, such as Leyline of Sanctity and... Leyline of Sanctity. Mulligan until you find one.
So how does the deck win?
62 cards. If that fails, Elixir of Immortality shuffles your graveyard back into your library, If your opponent has an old Eldrazi (or runs graveyard shenanigans), you can use Relic of Progenitus to shut that down. Most decks don't run multiple Emrakuls, so if you get the first one, you should be safe. If all else fails, Cruel Reality and
Ruinous Path
provide a clock, especially when paired up with the rest of your removal spells.
