Salient

70 cards is much too much. Drop the four Terramorphics and the Scarland Thrinaxes, which you literally cannot cast (no green mana).

Put four Cinderbones in there. It's your best card -- because it only dies to Exile, provided you keep the mana open, and because it pairs with your engine perfectly. Drop the Sickle Rippers and Emberstrike Duo entirely, to make room.

Fun deck!

Out of curiosity, have you given Oblivion Rings a whirl in it? I would think a playset of Rings would be strictly better than Solemn Offering and Holy Strength, unless you find you really badly need that four life or +1/+2.

I was surprised to see two Pithing Needle in the mainboard. Can you advise what you're targeting with them?

Of course, it also needs all the other tools that aren't in Standard.

I really can't see a full-on discard strategy being viable.

Adding blue would be impossible; this deck can't run tri-color. What it does need, horribly badly, is Dark Ritual.

Maybe an Angelic Wall, as an early catch-all blocker.

Angel of Salvation would be one to look into, and I'd run four Angelic Renewal. You'll be investing a lot of mana in each creature, so the ability to bring them back from a Terminate would be great.

Polymorph + Wind Zendikon would speed you up to turn 4.

Feedback on what aspect? We can help more effectively, with more specific ideas for you, if you help clarify what your goals for the deck are :-)

Well, you could start by not using the word "rape" in this context, from which any decent human being will turn away in scorn. You might even start receiving some helpful advice from the many female Magic players who populate these threads, instead of lectures on etiquette like this one. :-)

So close to being a goat purist... but not quite there. We need every last card in the deck to have a picture of a goat on it.

Why no Garruk?

Burning Inquiry with Megrim in play is fun.

Ahh, Sunforger. It's too bad that Restore Balance and Wheel of Fate are sorceries, really. Playing them off a Sunforger would be fantastic fun.

Why the Wojek Sirens?

As with Didley, I don't intend to be rude at all, but... you're telling us this beats Jund and Spreading Seas regularly? Really?

Even Vampires is hard to believe. Most competitive Vampire decks run Disfigure, which would eat your Ball Lightning and/or Bloodbraid. Are the folks at your local FNM just, y'know, not very good Magic players?

Wind Zendikon provides a convenient cheap Polymorph target.

I agree with the others who suggested your friend should either go full-bore discard control, or full-bore aggro sligh. And frankly, full-bore discard-control better suits a Blightning deck. It's the two-card discard, not the damage, that makes Blightning amazing. It's also cheaper to do well.

You (your friend) could use cards like Terminate and Lightning Bolt to eliminate creature threats, wreck their hand, and then grind them down with Specters. You might consider running a Bituminous Blast, since cascading into practically anything is wonderful for you.

Aww, 75 cards, and no room for Stoneforge Mystics to nab Kaldra components for you?

I'd suggest Vines of the Vastwood over Canopy Cover -- this lets you react to a spell targeting your Piper and protect it with shroud, and late-game it's two mana for four damage (hopefully).

Will the Scute Mobs survive long enough to be more worthwhile than Lotus Cobra? A turn-two Cobra, if left unanswered, gives you an early Piper and keeps giving each turn; a turn-two Scute Mob does nothing.

I'm not really convinced that Tsunami is worth splashing blue for all by itself. It's a cool idea, but you're giving up an awful lot by not running mono-green. I would run one Lurking Predators and three Rampant Growth instead. (Lurking Predators plus Oracle of Mul Daya would be great fun.)

To get down to 60 cards, I suggest pitching the four Piranha marsh.

Disfigure would be a great swap-in. It eats Steppe Lynx during the upkeep, it eats Bloodbraid Elf at instant speed, it kills Pridemage, and it helps ensure the opponent only has one creature out when you finally cast Gatekeeper, and it helps ensure that your creatures win trades -- mid-game, the -2 to power in -2/-2 allows for a variety of tempo-swinging surprise tactics that a -0/-2 wouldn't. Even given the "sack and bring it back" theme of your deck, I'd run Disfigures instead of Bone Splinters.

You might consider running a Vampire Nighthawk, maybe two. Since you won't want to draw more than two Ascensions in a game (they're too slow for a late-game drop for this deck, or any deck really), you could replace one of each with Nighthawks. Nighthawk is an immediate threat, especially as a flier, and it buys you time to put your Aristocrat-Highborn engine together. It also ups the Vampire count.

Given how many creatures you want to put in your graveyard, you might consider running one Quest for the Gravelord. It could drop a 5/5 on the table for you, in one turn (once your engine is running), for practically zero cost.

Don't forget a Hexmage or two in the sideboard, especially since there's only 12 cards boarded currently.

I guess you're probably pretty sold on using the Ambassador... Have you tried swapping out three Kraken's Eye for one Jace, the Mind Sculptor, and maybe removing a couple Islands? (Or perhaps playing something with Landfall, so additional Islands confer some benefit.)

I would have to disagree with every comment from ControlGame, except for the comment on shroud (which probably isn't as much a concern as CG suggests), and the comment on adding a color. A permissions deck isn't interested in playing cheaper, faster creatures, because mana needs to be kept open for permission. Also, Into the Roil isn't all that bad (relative to the other cards here), it cantrips when kicked; it annihilates tokens; it resets planeswalkers; it ruins levelers in RoE.

Also, it's absolutely not worth splashing for green to run Gaea's blessing (which puts you out of Type 2 anyway). You have nothing to fear from mill decks: you can counter or bounce their win condition, and you never search your library to trigger an early Archive Trap.
