Thanks for the feedback!
I chose to use Path over the spear for a couple of reasons, the first of which is that I'm not running Devotion anything, but I am running 4 mutavaults. If I keep a hand that has Plains Mutavault Mutavault as the lands, I want to be able to play it out with the path. Secondly, my red splash is for Akroan Hoplite, which encourages attacking with as much as possible every turn. Path also shares this encouragement, and can save me in a hyper aggressive mirror. While being able to remove creatures is nice late game, I don't really expect there to be a late game. Even if there is, I have Banisher priest and Azorius Arrester to get rid of big problem blockers.
In regards to Boros charm, it is definitely something that I considered. but unfortunately I traded away all 20 copies that I had accumulated back at the dawn of rotation when everyone in my playgroup was specing that Naya Hexproof would become dominant. As soon as I get some, They'll be in the Sideboard. I don't think that I'll be putting them main board because I feel that it's too obvious. 'A bunch of plains with some red splash, he's obviously running boros charm.' I believe that the opponent will be playing around it without me even having to show it, which will allow me to run more threats and answers main board. I could be wrong though, but this is at least what I have seen happen with other similar builds (I ran Jund for about a week, and all of my opponent were playing around thragtusks that weren't there).
I like Cavalry pegasus, but I would rather keep my 1 drops high. As I mentioned in my origional post, This is meant to act as a tempo deck, so I want to be playing as much as possible every turn, and by replacing a 1 drop with a 2 drop, I'm cutting back on my tempo potential. I will, however, be putting the pegasus in my sideboard to replace what is currently Viashino Firstblade, which is admittedly in there to help justify running red mana...
Nykthos is not really necessary here. I think it'd be a sort of Lili of the Dark Realms situation; Here's a bunch of mana, hope you have something to do with it. I do want to get a couple of Heliods though for the SB just in case things slow down for me and I need something to power through.
I think you're right about the Gideon, but I put him in because he provides a large body that evades removal in the control matchup. While Ajani is very good utility in the midrange / aggro matchup, I'm much more afraid of being shut out by board wipes and having to face an AEtherling. I want the Gideon because he is a constant, practically non-removable threat, whereas the Ajani doesn't do anything by himself when he's left alone after a wipe. Again, I may be wrong about this, but how I see it, Gideon is just so much better as a last resort card. I am very excited for the new Ajani that's coming in one of the later Theros sets though, and I really want to see what he can add to this deck.
I do have another question here, is Boros Elite something that I should be picking up? Sure, it's a 3/3 for 1, but the battalion is very situational, and he seems very unreliable as a 1 drop. Yet, I see a lot of the white weenie decks using him...
Again, thanks for the posts.
