So, now that I have seen the new Gideon, I think I have a plan for my standard deck once War of the Spark comes out. I am axing all the dominaria stuff that I currently have, so as to be ready for it to cycle out.

White Aggro!
3x Gideon
3x Tomik
4x Grateful Apparition
4x Adjani's Pridemate
4x Healer's Hawk
4x Tithe Taker
4x Venerated Loxodon
4x Conclave Tribunal
4x Dawn of Hope (or maybe only 3?)
4x Unbreakable Formation (I think that is the name... the give indestructable, with addendum +1/+1 counters)
22x Plains (or maybe have 20, and 2 mobilized districts, kharn's bastions or blasting zones?)

My meta has some really hard-core people, but we are also trying hard to get in new players.

Though this plan may change depending on what else shows up... and the nonbasic lands will probably depend on how much money I am willing to spend. I guess I will have to see how much gideon and tomik end up costing.
