Broken cards

[LinkCelestrial]

Lots of blue decks run {Omniscience}. I'm pretty sure it's an auto include in {Niv-Mizzet, the Firemind} and {Narset, Enlightened Master} decks. Free spells are amazing, especially with cards like {Enter the Infinite} and {Taimyo, the Moon Sage}'s emblem.

The only cards I feel are OP or broken in EDH are ones that were built with 20 life in mind but are now introduced into an environment with 40 life. For instance, {Sorin Markov} and {Magister Sphinx} essentially eliminate people from the game in a way that is insanely mana efficient (repeated blinking of Magister Sphinx is one of the most rage inducing things I've ever seen since it's abusing what is already a 4 to 1 plus damage to mana ratio). Other cards are not quite as obnoxious ({Serra Ascendant} and {Divinity of Pride} are annoying, but beatable, cheating in a {Felidar Sovereign} in the early stages of the game makes the whole thing feel pointless), but still give you insane bang for your buck. And then there's infect. Why the .love. don't they just make infect 15 damage in EDH? I've seen waaay to many people get killed by Rafiq into Putrefax gg. It's ridiculous, and one of the worst parts of EDH.

You've addressed two of my biggest issues with EDH in one post.
