Tymna Thrasios V.2 (EDH / Commander)

Proper mulligans are extremely important in this deck. A good hand will either have a combo piece and a tutor, some fast mana, and most importantly at least 2-3 lands.
The gameplan in this deck is basically just fast combos. This is the game plan.

Step One: tutor or draw into these cards and make infinite mana with one of these combos
Dramatic Scepter Combo:: Dramatic Reversal + Isochron Scepter + 3 mana from non-land sources = infinite mana of whatever colors your non-land permanents are tapping for
Vizier Combo:: Devoted Druid + Vizier of Remedies = infinite green mana (lightning greaves is available to use on the spot)
Bomberman Combo:: Auriok Salvagers + Lion's Eye Diamond = infinite mana of any color. While this falls out of the 2 CMC party, both pieces are still easily tutorable.

Step two: Cast Thrasios, Triton Hero. Draw deck with Thrasios's ability and the infinite mana we just generated.
concise win: find Walking Ballista and cast for infinite mana and shoot opponents to death.
alternate win: After drawing your library, use your infinite mana to play out all the artifacts. Now you can play any spell and loop your graveyard and library back together with Memory's Journey and Noxious Revival or Elixir of Immortality. Once you've looped your graveyard back into your library, you can draw the whole deck with thrasios again. Play Beast Within on an opponent's land to give them a 3/3, then cast Reality Shift to exile it and manifest the top card of their library. Now you can cast reality shit infinite times to exile all opponent's libraries. You can also loop Windfall to make opponent's draw out to death.
