This deck idea is all about getting the amazing Progenitus out. Time of Need allows you to search for Progenitus if he's not in your hand. The Elvish Pipers allow you to play Progenitus without paying its mana cost. Dramatic Entrance allows you to play a green creature from you hand for free. (Progenitus is technically a green creature) Aetherplasm allows you to swap in Progenitus to block a creature. And, if all else fails, you can get Progenitus out for his mana cost with Joiner Adept. Mirror Gallery allows you to have more than one Progenitus out at a time. All other cards are there to stall until you get Progenitus out.

Make it 60 cards. Also this doesn't seem like a rush, more like a stall.

If you look at how the deck is set up, you can see that card 61 is Mirror Gallery. This allows you to have both Progenituses, Progeniti (haha) out at the same time. One card will not upset this deck too much. The name of the deck is there for flavor.
Misty rainforest? How about some other dual lands?
If you want to, you can. I don't feel that I need to.
