Oloro Enchanted Lich (EDH / Commander)

This deck is about one thing: finding Lich and keeping it on the battlefield. After that let the jank flow through you with such classic combos as:

Aura Thief + Enchanted Evening + a sac outlet: steal everything!

Opalescence + Parallax Wave: exile every creature!

Opalescence + Parrallax Tide: exile all lands you don't like!

Opalescence + Enchanted Evening: No lands for anyone! It's kinda bad!

Solemnity + Decree of Silence: only you may cast spells!

Lich+ Ad Nauseam: Draw your deck!

Lich + Repay in Kind: Kill every non-lich!

Lich + Approach of the Second Sun: Win in style by not killing anyone!

Finally if you draw Mastermind's Acquisition there are a few spicy sideboard cards put in for specific reasons:

Ajani's Chosen: Enchanted Evening + Ajani's Chosen + Any other permanent ETBing: A draw!

Pariah: Stuffy Doll + Pariah (targeting yourself): A draw!

Anguished Unmaking: For removing enchantments that stop lifegain!

Dictate of Heliod: For when you want to keep your lands while nuking everyone else's with enchanted evening!

Windfall: For when you've Ad Nauseam'd and want to next level Lab Maniac!

plus a few hate cards because: hate.

Overall this deck is a giant teetering pile that doesn't do much other than not die a lot of the time until you do die. If you get Lich online with some protection (Solitary Confinement or Delaying Shield) you will be archenemy, guaranteed. At that point your whole game will be trying to outrace the cyclonic rifts and krosan grips that might come your way while keeping your Lichiness protected before finally winning somehow. Playing against a single counterspell heavy deck will probably eat up too many of your own counterspells and something will fail. It's a deck that swings for magical christmas land and sometimes gets there. Slowly. But often doesn't. And isn't fast enough to outrace anything built efficiently. And even once you've set up your Lichiness, the decks wincons are often slow and expensive to pull off, especially if you're holding up counterspells to protect it. But very little matches the feeling of true Lichery than sitting there, immortal, scheming for the long term.
