Swans of Bryn Argoll and
Chain of Plasma
combine for infinite card drawing (and discarding, to an extent), which lets you do tons of fun stuff. Providing you don't mill yourself.
Once you have most of your deck in hand, a lot of cool stuff can happen.
If you have enough cards, and the right mana, you can win same-turn with a huge
Conflagrate
flashback (conveniently discarded to pay for more drawing), or discard everything to amass a huge zombie horde using Zombie Infestation (err, this is more like next-turn, but still).
If you're willing to wait 'till next turn (after dropping a Spellbook or Reliquary Tower), you could then play a Skirge Familiar, discard everything for a huge Drain Life (or one of the better variants), and win that way. If you're looking for a different win condition, the Skirge Familiar also allows a lot of other mana-heavy funtimes; like, say, hardcasting an Emrakul, the Aeons Torn. Or four separate Kokusho, the Evening Stars (which would be the only way this deck would be even remotely good in multiplayer formats).
Things like Dark Withering,
Fiery Temper
, and the oh-so-fun
Basking Rootwalla
are in there to be discarded along the way.
The main problem of this deck is that it's a bit clunky, and to be fair, that is a big one. To help with that (somewhat), I've included Preordain, the classic Brainstorm, and a one-of Crystal Ball.
Another one-of shows up in the form of Elixir of Immortality, which is your only fallback plan if things go awry, but also works wonders simply recycling the combo.
Desperately need advice on how to improve the flow of this deck. Make suggestions!
