It is true that there are infinite "what ifs" in a game as open as Magic, but we know that there are certain cards we can expect to see in the most competitive formats. If we look at what is currently being run and why its effective, we can better prepare our decks to be more resilient against them.

Your deck tries to combo out by ramping mana, drawing cards, and playing into a win-con. There are going to be certain styles of decks that are more prone to shutting you off, which is why I'm bringing up these strategies in particular. Since your combo window is turns 4-6, you need to be worried about two things in cEDH. The first is people comboing out faster than you. We see this in decks such as Gitrog, Godo Helm, or even Grenzo. When these decks are consistently busting their combo turn 2-3, you need to answer or lose. Relying on other players to put a stop to a win attempt will prove unreliable, which is why its so important that you slot removal. Your turn 4/5/6 answer does no good when the game is over by turn 2/3. If you have no way to turn off their win, you are asking them to goldfish to a victory on you.

The second type of decks that will prove problematic for a turn 4-6 combo deck is stax, because their deck is designed to deprive you of resources and push your combo window so far back that you are unable to combo before they have won. They drop very fast and efficient heavy mana rocks, and then put down tax effects to make you unable to play. This specific style of deck can be hard for your build because they can lock you out of playing your draw spells, they can steal your draws, or simply prevent your draws altogether.

Let me give an example to show you what I mean.

Stax Example Show

Stax is a very common archetype in the competitive scene, which is why its so important that you try to stax-proof your deck. It looks to me as if stax can cause serious problems for you.

On top of taxing stax, there's another type that may shut your deck off. Heavy discard. An early Sire Of Insanity can hose your whole game, while Mindslicer can impact your card advantage enough to cause a loss. Multiple discard effects like Necrogen Mists Bottomless Pit Oppression landing by turn 2 will make your build extremely sad (Turn 1 Dark Ritual Cabal Ritual Mana Crypt + any producing land and drop two discard enchantments). Chains of Mephistopheles turns off all your big draws, so does Alms Collector or Notion Thief

Another set of cards I would recommend taking a peek at is recursion. It can help against discard effects that would otherwise shut you off, or serve as a 2nd/3rd/4th copy of your draw spell. Wildest Dreams would work surprisingly well in your deck, the mana aspect is negligible and lets you reuse multiple big draw spells from your graveyard, as well as recover from wipes. Nostalgic Dreams is arguably worse with the additional cost, but can translate extra basics tutored by your 3 cmc ramp spells into more draws. Regrowth is also fantastic.

I hope you don't mind the close inspection! I really enjoy your build, I'm just curious to know if you run into these cards and how you interact with them. Almost all the stax cards I linked are included in tournament proven cEDH lists with various commanders, so they're cards that are in the meta and will be played.
