I would recommend adding Felidar Sovereign to the deck for an extra win condition for flexibility, bigger creature, and life-gain source.It also fits with your budget.

I'd maybe look for ways to lower your average converted mana cost. 4.36 is pretty high. Good luck!

Sunbond would be a fun addition with all the lifegain... makes creatures huge quick, exponential lifegain and creature growth!

Sunbeam Spellbomb would help with that curve.

Rhox Faithmender for sure

Soul Warden Soul's Attendant?

Daxos of Meletis is an old favorite of mine. He's like another Augury Adept, except he has natural evasion and lets you draw from your opponent's library!

DarkStarStorm thanks for the tip! I just may try that out. :)

You have fun with him. I remember milling someone out with their own deck thanks to Daxos.

Reprisal is really good removal for mid to late game. It can also help lower your mana cost.

Sunbond + Goldenglow Moth

4x Lone Rider  ^Flip, -2 Rhox, -2 Guardian. More Field of Ruin. These are great in mono decks. Maybe some Disenchant and definitely some Stony Silence in sb.

Definitely don't run 4 Felidar Sovereign. You're going to want some card advantage engines as well, I'm a fan of Thraben Inspector and Ranger of Eos. Rest for the Weary and Chaplain's Blessing are not good cards. If you insist on running cards like that, I'd suggest Ritual of Rejuvenation and a cycled Renewed Faith as they replace themselves and let you dig deeper. Ajani Goldmane may be a planeswalker for you. I'm always in favor of more interaction, so i'd suggest cards like Oblivion Ring, Declaration in Stone, and Blessed Alliance. Dusk // Dawn might be a good sideboard card for you, while it hits a flipped rider, an ascendant, and a big kitty, it clears any meaningful blockers your opponent has and gets all your creatures (except the sovereign) back.

Mentor of the Meek could also be good

This isn't really the type of deck I usually play, but I hope it was at least a little helpful

Kabira Crossroads is probably a land you'd like, as would Shefet Dunes and Desert of the True

Healer's Hawk maybe?

Brave the Elements ?

I suggest dropping at least a couple of the Reviving Dose s for Rest for the Weary . The other instants offer card draw, and your main resource here is your life total, which you want to raise fast to get the full benefits of your win conditions.

legendofa, I did have that in and replaced it with Reviving Dose so I'll test out a little of both of them and see if it helps. Thanks!
