This looks like fun and strong white tribal deck +1. The only thing I would suggest would be some anti-walker tech in the form of Oblivion Ring. Other than that I personally think that your deck looks solid and pretty reliable. Kudos on a cool deck.

Swap the Brave the Elements mainboard for Path to Exile from the sideboard, it is much better game one, drop the Elspeth, Knight-Errant for a second Gideon, Ally of Zendikar

Current Landbase:

4x Cavern of Souls4x Field of Ruin4x Flagstones of Trokair8x Plains

Optimized Landbase:

4x Cavern of Souls2x Ghost Quarter4x Flagstones of Trokair1x Windswept Heath1x Flooded Strand1x Marsh Flats7x Plains

I respectfully disagree. After much playtesting ive found I dont depend on creature removal as much since tribal decks can generally overwhelm an opponent and whatever creatures they have out. Which is why my creature Removal is a side board.

Field of ruins is vastly superior to GQ in competitive play.

Fetch lands are unnecessary since Im mono white and 8 of my lands already thin out the deck.

Elspeth is a beast. May not be as good as Gideon but shes good fornreason listed above. Plus it open up the possibility of having them both on the field at once.

Have you seen the Dominaria Spoilers? This deck's going to be loving it. Here's the link to the spoilers, and some neat cards to look forward to are Kwende, Pride of Femeref, History of Benalia. Also, Grand Abolisher is a neat card to at least sideboard to help keep meddling control decks from annoying you! Love the deck, best of luck!

Oh another I just saw was Benalish Marshal. And I just realized Grand Abolisher wasn't a knight sorry.

Hey dude love this deck! I have a few suggestions. You don't have to put this in but it seems good and that card is Hero of Bladehold. Another card you should put in is 2 Dismember's in the main maybe in the side. Another card you should definitly have four of in the main is Mutavault. The last card is History of Benalia. It is new so maybe wait a few months a see how good it is. My last question is why are you running Elspeth, Knight-Errant

AWESOME +1

I very much like the deck, seems really good. One thing I would like to add is that Settle the Wreckage seems like it would be better in the sideboard than Wrath of God. The downside is real but the ability to exile and have it only affect your opponents creatures makes it better in my opinion.

Wrath of God is better since you can make your creatures indestructible with exemplar imo. But its not a bad suggestion.

Although a Board wipe at instant speed is pretty sweet. Just hate the idea of blowing up my opponents mana pool.
