Yeah, you need forests for the fetch lands to fetch as well as needing them for mana sources.

Unless your opponent has Ash Zealot out.

Sideboard needs to have exactly 15 cards.

Although very unlikely to draw

Perfect Hand Opening: 4 Dark Rituals, 1 Relentless Rat, 1 Thrumming Stone, 1 Swamp.

This deck was originally meant to be an all 1 drop deck

Thanks!

too bad Mox Jet hasn't been reprinted

even if you swap 4 cards for Dark Ritual?

If you took out 6 of the lands it would only be a 60 card deck, and would still have between 20 & 24 lands

I would also suggest Dark Ritual (4 of them) that way you could get the Thrumming Stone out faster

I think 27 lands is a wee bit much. I would personally only go 20-24 lands in a 60 card deck.

There's an older rat that has it's power and toughness equal to the number of rats in play, but doesn't have the activated ability. I can't think of the name of it though.

I was just gonna suggest adding Thrumming stone =)

Royal Assassin is an improved version of King's Assassin.

There quite a few good goblins out there, I like the ones from the Scourge and Onslaught sets. I would suggest: Goblin Guide (Zendikar), Goblin King, Mogg Flunkies, Reckless One (only if you have a bunch of Goblins/goblin tokens out on the field), Bloodcrazed Goblin. (Don't know if you heard of Goblin General or not but he is too hard to get ahold of these days, and isn't worth it unless you can keep a bunch of goblins on the field.)
and congrats on getting the Piledrivers those are expensive cards.

Yeah, if I actually made this deck it, would probably be all Proxies

If you play Rift Bolt for its suspend cost, it only costs 1 Mana, with only 1 time counter on it.
With that in mind, the Mana Curve is kinda Misleading.

Instead of Fyndhorn and Elves Llanowar Elves; I would have Elvish Pioneer and Wood Elves
