So I have been playing for a month so I am still new in terms of deck building experiance, I bought 3 boxes of M15 so most of my collection is M15, so I need a bit of help with my deck, I am not sure if its better to go mono white or keep trying white green.
Anyway Ill post my deck list and if you have any suggestions keep in mind I mostly have M15 stuff so dont suggest cards from older sets, any help is greatly appreciated.
