Uses Aluren + Cavern Harpy to combo out a win.
Parasitic Strix will bleed the opponent of two life - but more importantly, it will gain you two life. Use one of those life to return Cavern Harpy to your hand, lay it again for free (Aluren), and pick up Parasitic Strix. Repeat until opponent is dead.
Coiling Oracle and Raven Familiar creates massive card advantage to pull out the Parasitic Strix.
Selkie Hedge-Mage gives you infinite life so you can survive a couple of turns if it all goes nippley-bits up.
Brainstorm, Intuition and Lim-Dul's Vault all help to pull the pieces out.
It is possible, though unlikely, to see the combo out by turn three.
1) Lay a dual land (preferably Tropical Island).
2) Lay a dual land, (If you have a Tropical Island out, it doesn't matter which.), and tap for a green and blue mana to play Coiling Oracle, and pray you draw a land card with its "comes into play" ability. Put that land into play.
3) Lay a dual land (by this point you need two that tap for green mana), tap all for Aluren and use Cavern Harpy to bounce Coiling Oracle to reveal the rest of your library at instant speed.
4) Wear your most cheesy smug smile as your opponent realises that he or she just lost to a crazy combination of "comes into play" abilities!
