My attempt at cedh.
Each CEDH deck needs turn 0 win. How about a deck with all of them.
Academic Rector is broken
Put down a Plains or a Swamp.
Play Mana Crypt and Lotus Petal. Lotus Petal will give you either black or white depending on which of the two lands you don't have. Also exile Elvish Spirit Guide for a random green and like a fool tap everything and float all of your mana. This is turn 0 so unless the other player has a 0 cost counter then who cares.
You now have 5 floating mana. One is white and one is black (land and lotus). The rest who cares (2 from crypt and one from guide).
Use 1 black to play Viscera Seer and 1 white and all others to play Academy Rector.
Sac the little dude and go bring Omniscience before the game even begins.
From here on you know the lyrics. Play Enter the Infinite then Laboratory Maniac for free and any draw and you win. Congratz. Had fun?
Same, same. But different.
Again Mana Crypt and Lotus Petal but this time use the crypt to play Arcane Signet. You can now generate 2 blue and one black, expecting that you played a land you nimrod. Use the black to play Demonic Consultation and then the 2 blue to play Thassa's Oracle. Again gg.
This is getting smelly
Play the the two 0-cost mana rocks again. Common pattern, I know. If you did not get a swamp this can also be done with Arcane Signet. You should now have 2 black mana and 1 other. We need 1 more mana of any color so Sol Ring or Elvish Spirit Guide will do. Now we have 4 mana in total. Use 3 to play Buried Alive and bury Necrotic Ooze, Phyrexian Devourer and Triskelion. With the last mana, which hopefully you figured out it needs to be black, we cast Reanimate and bring back to life the oooooze. Now you can reveal your deck for a spicy victory.
How about some infinite mana to do anything.
I don't want to repeat my self so generate a total of 6 mana. One of those must be green, 2 red and the rest who cares. Play Food Chain and Squee, the Immortal and voila, infinite mana.
I be firin me lazorz
Generate 5 mana + 1 land, 2 need to be white/red and 1 red. Play the Basalt Monolith and tap it for some refund. Then play the Zirda, the Dawnwaker and start producing infinite mana. Play Staff of Domination to filter and find Simian Spirit Guide to give you that extra umph that you need to blast away. With the infinite mana and your last red blast em, and the table next to you with a simple Fireball.
