Erebos, God of the Dead-> Drain life,draw cards,win game. Also, some shadow creatures mixed in for fun
Kruphix, God of Horizons->Ramp into big stuff and smash the opponent into the ground.
Phenax, God of Deception->play some walls->tap them walls->mill opponent. It also contains some snow permanents and interactions for fun.
Sidisi, Brood Tyrant->Put stuff in my graveyard-> create zombies and other stuff->win game.
Niv-Mizzet ,Dracogenius->Create chaos and maddness. I don't expect to win any game with it.
Sharuum the Hegemon->Create artifacts->Give them counters->use counters for their abilities->Win game. Either that or create an infinite loop that ends up giving me infinite turns and some tokens in each of those turns. Eventually that will win me the game as well.
The Phenax deck can defiantly be optimized, right now there is one card missing that should be in any Phenax deck and I'm missing some good creatures with the "inspired" keyword on them. (Like the one that turns stuff into gold)
The Erebos deck is probably unplayable in multiplayer as it will attract too much hate from the other players.
The Kruphix deck only makes use of 1 aspect of Kruphix right now as I don't have enough cards to make use of the no maximum hand size part of kruphix.
For the Sidisi deck I'm planning to put in a LOT more self mill. I want to be able to reliably empty my library and put in a few more cards to put cards back in. Being able to stack my deck exactly as I want to sounds exactly like how I want that deck to operate.
Niv-Mizzet may end up getting dismantled. It all depends if it is actually fun to play or just drags games on for too long.
And the fear I have with the Sharuum deck is that I spent too much money into it. I already never won any games with it because people feared it and banned together to kill it before it could do anything. So... giving it an upgrade may not have been the right thing to do......
Also, to make this happen I dismantled some normal decks. These include:
My first deck->Erebos (Both play pretty much the same as well.)
snow discard->Phenax and Erebos.
old standard Sultai -> Sidisi
An honorable mention to my old vampire commander deck. It got dismantled long before I made these new decks but quite a few of its cards ended up in the Erebos deck. It too never won me games because as it turns out, people are willing to band together if it means that they don't have to sacrifice a creature every turn again
