A refined version of Dragonlord retreat to utilize utopia sprawl's synergy with follower and arbor elf. To see the original list go here: http://tappedout.net/mtg-decks/dragonlord-retreat/
The deck has a few central lines of play that are affected by adding elf and utopia.
1.Combo: elf or utopia, knight, coralhelm.
2.Get geist through: elf or utopia, geist, planeswalker is nearly as strong as the combo itself and only a turn slower, typically. Similarly, geist + knight can find protection or unblockability via lands. In total there are 14 cards capable of allowing geist passage to the red zone (Elspeth, tamiyo, knight, steppe, rogues passage, coralhelm). Draws with multiple noble hierarch also allow geist easy passage via exalted.
3.Early ojutai with protection: ojutai is a difficult creature to use in modern. It is powerful and unexpected in a creature deck, but it requires a lot of enabling cards to be at its best. This deck is the only deck that benefits from playing the 12+ enablers it needs. Lines include: elf, follower, ojutai; elf, knight, sac land with knight for t3 ojutai, make sure to grab minamo with the ability for protection; elf, coralhelm, 2 fetchs enables landing ojutai t3 with protection; t1 utopia, t2follower, t3 ojutai
4.Finally, if a large number of bodies are drawn or produced, gavony township is a good way to close the game. Knight can tutor for township. This makes one knight activation and Elspeth into a grinding engine. Plus, this deck can also drop t2 Elspeth with an arbor elf + utopia draw. This does nothing to combo or big mana, but it is crushing to most fair match-ups.
