Well, for one, the current version you've linked is even further from being standard legal than before... but you said that didn't matter all that much.
I can see some cards that you should yank and it would be possible to move it to standard legal with a few changes. To start,
Birds of Paradise can be switched to
Elvish Mystic. Sure, it's only green, but it's standard legal. Although you could easily argue to slide in
Arbor Elf if you have the proper shocklands too.
Nip Gwyllion could easily be replaced by
Trained Caracal for a one-drop lifelinker.
Giant Spider should be dropped for more
Vampire Nighthawks as they're hands down better cards - they block just as much, gain life, and can kill just about anything out there.
Heroes' Reunion is just plain bad. There are countless ways to gain life that would be more reliable and useful.
Explore/
Rampant Growth could easily be changed to
Farseek.
Make those changes and you'll be quite similar in play, but standard legal. Now, that being said, the deck isn't exactly what I'd consider ideal or very competitive by any stretch of the imagination. I would suggest taking it more towards the B/W humans or aristocrats builds with
Exquisite Blood and
Vizkopa Guildmage as an alternative win-con... but that's just me.
