Boros!!

I'm building a Boros deck for standard this is what I have for the core of the deck;

4 Steppe Lynx
4 Goblin Guide
4 Ranger of Eos
4 Plated Geopede
4 Kiln Fiend

20 Creatures

3 Earthquake
4 Lightning Bolt
3 Emerge Unscathed
4 Path to Exile

14 Spells

4 Arid Mesa
4 Scalding Tarn
4 Marsh flats
2 Terramorphic Expanse
5 Mountain
4 Plains

23 Lands

I have some play, I'm trying to think what to throw in for the last couple slots.

Few Ideas;
Ajani Vengent
Staggershock
Survival Cache
Baneslayer maindeck?
Bushwacker
Student of Warfare
Ceredon Yearling
Hells Thunder
Various Burn

What do you think?

I think for a deck like this Bushwhacker is a necessity. I mean the deck used to be called Boros Bushwhacker.

It allows you to store up fetch lands on the board, drop a Lynx and/or Geopede with a kicked Bushwhacker for a huge surprise swing.

Not sure about the Emerge Unscathed. I like the idea of it with Kiln Fiend...pretty sick, however you're gonna want more creatures less spells.

I would move the Paths to sideboard because it will ultimately help your game 1 vs. most decks. You would probably side them in a lot for dealing with Kor Firewalker, but winning game 1 is really important. I would go

-3 Emerge Unscathed
-4 Path to Exile (moved to sideboard)

+4 Goblin Bushwhacker
+3 Staggershock (it's removal and it's close to doing what Emerge Unscathed does for Kiln Fiend just in a more aggro way)

I could see some sick turn progressions too....

Turn 1 Steppe Lynx
Turn 2 Fetch, Swing for 4, Kiln Fiend
Turn 3 Fetch, Staggershock, swing for 8...(14 dmg by turn 3 seems....well seems something)
