Deck list, HELP!

Please help!!

4 serra accendant
4 wall of omen
4 hero of bladehold
2 baneslyer angle
2 suntitian
1 elspeth tirel
1 guideon
4 condems
4 brave the elements
4 journey to now where
3 day of judgments
3 honor of the pure
20 plains
2 emeria the sky ruin
2 mystifying maze

I say run four Sky ruins instead of any mazes.

i like the maze. with the current meta it can be useful. it un equips anything with a sword, kills tezz creatures and prevents a lot of damage from boros creatures. plus other random things. i think it is an underused land if you dont mind the colorless mana.

but to help the deck out i would (i hate to say it....) run the stoneforge package if you can...and maybe splash a color?

red would give you access to the best removal in the format (at least i think so..)
black gives you awesome hand disruption via discard spell and good removal
blue allows you to have counter magic and draw power
green would allow you to maybe run a shaman package or go for a more aggro build

but if you want to stay mono white maybe try students?

I think you need to commit either to a more aggro build- such as Quest WW. WW has no real bad match ups, allows for crazy 2-3rd turn kills. or go more control and go like RW control, using 3 elspeth, 3 koth , bolts, day, slayers, squad hawks, and the likes. if you go to mtgsalvation and look under block construeded their is a RW control deck that is dominating the format. WW is nice cause its so cheap though

Your deck needs improvement not to be changed into a whole new deck. Build those other decks if you want to play them. Your white deck is not a complete loss. You can win with it. Try some adjusments. Like take out the mazes and see how your deck runs or try splashing some color. I think splashing color could hurt the way your deck plays but try it out. There are some better creatures to use from the set that you havent tried yet. Like Mirran Crusader or some artifacts. Figure out what you want your deck to do and look for creatures and spells to make that happen.

something you may want to look at...
im not advocating net-decking or anything and i think your deck is better but it did surprising well! so maybe there will be something here you like.

anyway
