If you do run green, and this much green, you NEED more green sources. 4 is not enough. Cut some 3 plains and 2 islands for forests. Or get more guildgates. I do like the Simic Charm s in here, that's smart.

Oh yes ofc need some more green mana sourced, made the deck yesterday and think I missed going over the mana base :)

Ha ok, I get that, and have done the same thing before myself.

But what do you say about dropping green and instead gor for silverblade paladin, champion of the parish and some detain creatures( like that white arrester dude) and spells?

Ummm. I think your power level will go down a good chunk, but you will have a more consistant deck. I like the green personally. I've never seen detain work out that well. Silverblade Paladin can be insane, but he is fragile, and it's sad when it's instant speed killed and it's buddy loses double strike too. I'm not saying don't run him, cause he's definitely good, just be cautious.

Any suggestions of control-ish cards that would fit the deck?

i would drop both mythics and Ascended Lawmage for Silverblade Paladin i have a deck similar and silverblade means that i only have to be able to swing at my opponent twice with a power five creature to win

If you cut the Voice of Resurgence the reason should be that you traded it for a bunch of other cards you wanted. It is definitely good in the deck.

Sphere of Safety ,since you have so much ramp anyways.
