Heroes are a linear strategy. Ideally, you want every card to be a hero, or to trigger one. Excoriate does neither. Our first pick is wasted outside a heroic deck. There will be packs where we won't be able to pick a hero or an enabler, but while we can, we should pick them. It may not work, depending on what our neighbors are drafting, and we may need to go three colors.

Alternatively, we can just draft a pile of good cards and hope here will be a deck in there.

Even a hero deck needs removal Zleht.

Not if it's aggro. Then you just turn creatures sideways and use combat tricks to kill anything that dares to block. Removal just gets in the way of killing your opponent. If a white heroic players has the mana and time to play Divine Verdict, something went wrong somewhere.

I haven't much experience with green heroes, but white are aggressive and need to attack, since otherwise they get outclassed. And our green is a one-drop that fits into an aggro strategy, and needs cheap tricks to be relevant. That green devotion pump spell somebody suggested is ideal.

Pack 1:

Hero of Leina Tower
Excoriate

Next...

Skyreaping
Eternity Snare
Ashiok's Adept
Kragma Butcher
Impetuous Sunchaser
Weight of the Underworld
Divination
Elite Skirmisher
Scouring Sands
Fall of the Hammer
Charging Badger
Oreskos Sun Guide

This one is much harder. I'm for the Fall. It's removal that triggers our heroes.

I agree about not needing removal in a heroic deck... just like to hedge the first few picks.
Fall pretty much is the best heroic enabler though... In THS it was harder to get good enabler than heroes (beyond the bomby ones).

I think I continue to hedge and take a fall. But maybe this is why my draft decks are mediocre.

Take the best card in the pack through like pick 4.. and by then a pattern should emerge.

Fall of the Hammer.

I wouldnt be sad to go heavy GR and splash white for excoriate.

I think it's absolutely fall here guys.

Fall for sure. With some extra mana, fall works amazingly with our first pick hero. How big is your creature?

I don't want to take a Red card after passing all that quality Red. Signaling is very important in a Set with a low number of playables like BNG.

Skirmisher.

Have our first two picks really passed that much good red?

It's almost impossible to read signals via the first two picks, beyond, "Oh they took a rare."

Pack 1:

Hero of Leina Tower
Excoriate
Fall of the Hammer

Next...

Ashiok's Adept
Kraken of the Straights
Ephara's Radiance
Great Hart
Hold at Bay
Deepwater Hypnotist
Setessan Starbreaker
Nyxborn Shieldmate
Scouring Sands
Cyclops of One-Eyed Pass
Swordwise Centaur

Hate this pack. No bomb, no good removal... no evasion for us... so its just extra crap. And that makes it between Shieldmade and Centaur.

Nyxborn Shieldmate I guess.

That kraken sounds like a bigot to me.

I'll take that shieldmate.

Swordwise Centaur

I don't mind being almost mono green in triple BNG.

Ashiok's Adept!

Let's go for that 5 color hero deck.

Centaur. White seems not as good when we are not expecting phalanx/hoplite/wingsteed in packs 2-3.

Centaur. Card is good.

But white's bestow cards are pretty tasty. Granted so far we only have Tower Hero. I say shieldmate.
