Hmm, I'll have to keep that in mind. Rancor and Bonesplitter do essentially let me make my attackers disposable since Rancor always comes back to your hand from the graveyard, and Bonesplitter can simply be re-equipped, so that's good. Though I think I may keep Vines of Vastwood over Groundswell if not only because it makes the target effectively hexproof for the turn it is cast as well, though this costs 2 mana rather than one.
Silkbind Faerie is surprisingly a fucking nightmare for a lot of creature decks, and would be my go-to swinger, in fact. Swing on your turn for flying damage, then pay 2 on your opponent's turn to tap their biggest beater and block another with the faerie. It's amazingly cool disruption. Pestermite is a similar case, being flashable for a quick disruption tap or untap. I can effectively cast it for 2 as an emergency blocker and untap one of my lands, which could give me extra space for a quick pump spell for survival's sake or counterspell, or even Spellstutter Sprite. I'm a huge fan of Silkbind and Pestermite for that reason, and I'm half-tempted to find some way to sneak Silkbind into my Modern decks for how disgustingly disruptive it can be.
Faerie Miscreant is a tough choice for me because it's only ever worth anything if I manage to come across multiples of itself-- otherwise it's a boring 1/1 for 1. In fact, I used to run those until I realized that Delver of Secrets, despite not being a Faerie, is just straight-up better. I could see myself trying Dream Thief or Surveilling Sprite though.
And is my card advantage really that bad? I'm running 8 of the most useful cantrips in the whole meta-- though I could make an argument for running Halimar Depths for extra assurance.
As far as Moment's Peace goes, I'm actually considering running that in my own sideboard-- and that's something I can counter with Counterspell or Spellstutter-- which should be fine unless they're dead set on spending 5 mana to stop damage for a turn.
But I like your idea of dropping the pump instants and throwing in more permanent boosts. Rancor and Bonesplitter are permanent threats rather than one-turn threats, so that's always nice. Ancestral Mask could work nicely too, especially if Rancor is already on the field somewhere-- anything I attach it to would get +4/+4, which is really nice. Maybe I could run some Abundant Growth as a pseudo-cantrip that gives me an extra enchantment on the field-- or Utopia Sprawl could effectively give me more mana to work with and give an enchantment boost. It's all pretty messy though when not making a deck centered around that idea-- my friend runs a Bogle deck that uses assloads of enchantments for huge buffs, so I know how that works.
I'm actually really happy about Eternal Masters all of a sudden-- since Rancor is getting reprinted, perhaps its price will drop.
EDIT: I tweaked the deck somewhat. How does it look now? I'm suddenly getting the feeling I don't need this much green in the deck now that Mutagenic Growth and Groundswell are out.
