Hey man, looks like a solid start! There are definitely some tweaks to be made though, especially with you topping out your curve at four 6 drops, 20 land is not going to cut it, even with 8 mana dorks. Unfortunately I would recommend you going up to 23-24 range. The one of Ranger's Guile could just be another Boros Charm . I would remove the Spear of Heliod as to me it's a bit of a win-more in a deck like this. You have large enough fatties that the anthem abilitly is kind of irrelevant, and you should be doing the attacking most often so you don't need a stick to kill creatures that do damage to you. Those slots would be better filled with some more removal, IE Selesnya Charm for opposing fatties and Gods that get their devotion. Mizzium Mortars should have a home main board also! Hope that helps get some thoughts goin for ya! +1 for Naya, feel free to hook mine up also! Cheers!
