What is your favorite edh combo

[Varatius]

So i was sitting at work and was thinking you know there are some fun do nothing combos as well as fun do little combos and i was wondering if anyone had a combo the found or had seen that was very weak if impactful at all.  I'd also like to hear about any favorite multicard combo that needs 5 or more cards because i am just curious and maybe if i like any of these i will try to make a fun deck that includes them.

The massive Ramos combo is back.

I've never seen a do nothing combo, and I've also never seen a 5 card combo that didn't have a way of searching for the pieces built in.

It doesn't do nothing. You get infinite mana and infinite draw. There are a large number of cards you can stick in that win the game after this (Impact Tremors, Altar of the Brood, Laboratory Maniac, etc.).

[Varatius]

Sorin Markov's -3 with Wound Reflection out. It's kinda funny to watch someone be like "wait, what".

Why would u downvote that

I've never seen a do nothing combo, and I've also never seen a 5 card combo that didn't have a way of searching for the pieces built in.

The best do nothing combo is Jackal pup+ Indestructibility+ Pariah's shield
This creates a mandatory infinite loop that does absolutely nothing however im sure you or somebody could find away to make this a wincon which i would absolutely love to make happen.  FOR THE MEMES!

Since its an infinite combo the game would result in a draw.
But if you like stuff like this, what about Stuffy Doll + Guilty Conscience? as soon as the doll gets damage, the choosen player is dead.
