Deck Build Challenge (Return of the Wildspeaker) (Historic)

Generally, if you play green and you are looking for card draw people turn to The Great Henge. This makes sense, it is a very powerful card. I believe it has greatly overshadowed another very powerful card: Return of the Wildspeaker.

Return of the Wildspeaker is no joke. I've gave it a run in a couple decks now, just to see how it performs. I can honestly say I've never drawn into it and said "I can't use that". Truth is if you can generate 5 mana and it has no uses then you are probably so far behind with your green deck that you are done for anyway. The card is so flexible: 1) if you have a nice board state then anthem it up and finish the game 2) very little board state, then draw a nice hand of cards off a creature (like I said you have to have at least one creature at that stage or you are in a world of hurt anyway.)

What does a deck focused around this card need to play:
a) Lots of creatures that are non-human
b) Creatures with decent power levels to pay off the card draw.
c) Acceleration, it's an aggressive card that costs 5 after all.

Directions the deck can go (so many):
1) Gruul (Embercleave and an aggressive go wide strategy with big hitters at top end of curve)
2) Golgari (Rotting Regisaur and flyers)
3) Selesnya (Venerated Loxodon deck of non-humans, may miss on card draw though)
4) Multiple 3 color combinations (splash for Embercleave or other threat)
5) Mono-Green (from my experience you need to be running more removal then green alone offers).

Issues:
1) Burning-Tree Emissary is a human.
2) Token from Lovestruck Beast is a human.

Additions:

1) Elvish Mystic
*might be the best creature in the format.

2) Embercleave
*alternate win con, also a lovely card to draw into with RotW.

3) Questing Beast
*Big payoff for Embercleave and haste attack turn three.

4) Lovestruck Beast
*Best play available off of an Elvish Mystic on turn 2.

5) Paradise Druid
*need another ramp piece that fixes for red. Nice that it survives to accelerate our threat.

6) Domri's Ambush
*finish out the support slots with a removal piece that allows us remain aggressive.

7) Gruul Spellbraker
*more haste, trample is a major asset, decent evasion. Great Embercleave target.

8) Rekindling Phoenix
*Excellent 4 powered flyer that is tough to permanently remove.

9) Bonecrusher Giant
*I wanted another 3cmc creature for Elvish Mystic, nice body that doubles as removal.
