DESCRIPTION
Turn 1: Birds of Paradise.
Turns 2-3: Set up multiple mana from Harbinger, Knotvine, special lands, etc.
Turn 4: Be able to play any card except Progenitus. AKA be able to produce all 5 colors by turn 4.
Before Turn 7: Get out Progenitus from either Maelstrom Archangel or Mosswort Bridge.
Cascades are there to help speed up the deck to get less lands out once you have enough multicolor momentum going.
No turn 2 cards because part of the point is getting BoP out on Turn 1 to help speed up the deck.
This deck has little anti threat, so the sideboard is pretty open for that reason. Green should still be the choice color, since it is essentially the heart of this deck.
This deck is slow until around turn 5 or 6.
Win conditions would be attacking with Progenitus and friends, cascading enough small creatures to swarm with, any creature with 5 power plus Mayael's Aria after a few turns.
Note: lands are a problem, since many are slow in an effort to curb the cost of the deck.
