Updated again :)

aren't there really good token makers in modern? they might be better than some of the creatures you have here. 

path to exile ramps the opponent, tectonic edge slows them back down. seems pointless. dump the edge?


grand arbiter while awesome doesn't seem great. surely there are better white creatures available. 


I imagine swords are still good. add those. 


I don't play modern, i don't know what i'm talking about.

competely illegal league deck. How did you get these cards? You dirty cheater! We are going to expel you.


Seriously though you have no token makers but sundering growth? that doesn't make sense. 

Here is final version....I think......

Possibly more constructive feedback:


Looks like you want a fast aggro deck.  Thoughts:
- Lose Steppe Lynx for something more reliable.
- Lose Arbiter for something with more punch.
- Mind the human/Champion interaction (avoid non-humans OR Champion).
- Honor of the Pure is the last card to add, I think.  If there isn't something better in the slot, add it.  Don't take out a really good card to add it, though.
- Remove the Suppression Fields for something with more impact.
- Land seems about right.  If you curve at 3, you can get away with less.  Not needed, though.


Going aggro:
Accorder Paladin, Blade of the Sixth Pride, Daring Skyjek, Isamaru, Hound of Konda, Savannah Lions, Soldier of the Pantheon, Spirit of the Labyrinth, Student of Warfare, Thalia, War Falcon*


Bonus Gas Tech: Immortal Servitude


Bill, might I interest you in some Allies?  Tribal? Check.  White?  Check.  Lifegain?  Check.  Viable?  Check.  I mean, they seem perfect for you.

I think that this is better.  I do not like Steppe Lynx without fetches.  I've tried.  It ain't pretty.  I'm not sure I like maindeck hate like Supression Field, but you're the Modern guy, not me.  Honor of the Pure seems bad outside of token swarm decks.  I still think this tries to do too many things.  Is it a swarm deck (more tokens)?  Is it a hatebears deck (more bears)?  Is it a Martyr-Proc deck (more lifegain)?  There are lots of ways to take white, but I'm not sure you can take it all ways.  Also, if you like Weenie Swarm with an edge, just gander at Quest for the Holy Relic.  I think it pops up from time to time.

Updated, I am liking what I am seeing.

You are never casting True Conviction with 22 lands in Modern.  Unless I'm missing something...  I don't like Pithing Needle in the mainboard.  I'm not sure on Windbrisk Heights.  Seems like more of a Tokens card.  This seems pulled between Hate Bears, Tokens, and traditional White Weenie.  Dryad Militant does not stop Living End.  If you are really concerned about Goyf and Living End, I'd suggest Relics if you need more than RiP.  I do feel that Militant is underused, so I like that card.  Someone with more Modern knowledge than I have can speak to this, but I'm not sure I like Ghost Quarter.  Something more like 18 Plains, 4 Tec Edge for low curve, 20 Plains 4 Tec Edge for high curve seems likely.
