Just wondering why you have exalted cards thrown in there..

Knight of Glory was in this deck because of the protection from black but I guess that would be specific to meta game which would mean sideboard or another card.

-4 Knight of Glory +1 Knight of the White Orchid +3 Knight of Meadowgrain

Any suggestions of other cards I should use instead?

You ask'd for me to take a look on it. Well, there's really not much to say then, if you don't win T4/5 with a knight deck, it's junk. Which means that DON'T bother about drops above 4 mana. Running Spear of Heliod as a singleton, would never benefit you. Not having at least 3 Kinsbaile Cavalier , why even then bother trying, he is you wincon by far. Why Exalted cards, you would never ever only attack with one knight after T2. Don't need to worry about counters, so no need for Cavern of Souls either. You don't want to waste mana on buffing creatures, when you could just win, so no need for Honor of the Pure , this isn't a token deck. Fiendslayer Paladin is to expensive for mainboard.Accorder Paladin as a 4 of, is like 1 too many. Never underestimate the power of a 2/2 2 drop flier, but well, I might not agree about maining him, but not a bad choice at all.

Consider dropping one of the Kinsbaile Cavaliers for another Mirran Crusader. Also you may want to get rid of Accorder Paladin to add a little more removal, possibly mainboard your Wrath of Gods.

Callmegkill I took that advice dropped 2x Accorder Paladin and a Kinsbaile Cavalier. I added a third Knight of the White Orchid and fourth Mirran Crusader as well as a mainboard Wrath of God. I added Kataki, War's Wage to the sideboard. Thanks for the advice!

No problem! I've been working on a Knight deck as well and I've found that turn two it's usually better to be leveling Student of Warfare rather than playing Accorder Paladin. And Wrath is a nice surprise since people aren't expecting a board wipe with an aggro deck, but Knight Exemplar makes that play a possibility. Also, since creature removal is a bit more possible it may be better to have 3 Stony Silences in your sideboard rather than having Kataki, War's Wage as a one off--especially since he's not a knight.

I'm not sure if I own a 3rd Stony Silence I'll have to find one. What is your experience with Honor of the Pure? I seem to have mixed results.

Honor the Pure has been kinda hit or miss with me as well. I feel as though it's only worth it if you run either 3 or 4 of them and works really well in conjunction with Knight Exemplar if you can get them both out. Spear of Heliod or various equipment artifacts may be a better direction to go, however that being said if you go that direction I'd commit to it fully adding 4 Puresteel Paladins and at least 10 artifact equipment cards along with at least 3 Steelshaper's Gifts.

I used to run 3 Honor of the Pure and 1 Spear of Heliod. I have an artifact deck already Puresteel Delight. I keep that completely separate from this, which is tribal knights. This is not to say the equipment isn't useful. I would have to find a way to merge the two decks which would likely result in a 3rd completely separate deck. I have also considered using Angel of Jubilation as support instead of honor of the pure. But I still am not sold on that idea.

I'd use Honor of the Pure over Angel of Jubilation simply because it's a 2 drop rather than a 4 drop and I'm assuming you'd like the game to be over as quickly as possible since this is an aggro deck.

I would definitely put in a Leyline of Sanctity and Kor Firewalker for the sideboard. Leyline and Firewalker is good for RDW, and Leyine is also good against jund, or any kind of discard deck.

Leyline of Sanctity is a great call, I put Kor Firewalker on the sideboard for now. I am not sure if I will use him or not, but it's a good idea. Thanks!

4x Flagstones of Trokair in exchange for 2x Windswept Heath and 2x Plains perhaps.

Thanks Kjartan, great way to filter lands more quickly. Will have to obtain at least 2.

You need silver or white knight and Fiendslayer paladin for protection. Overall great deck. Could you check out and score my decks?

@RochanDragonmaster, Silver Knight is not legal in modern. White Knight is good but it is not as good as Fiendslayer Paladin which I have 4 in my sideboard encase they are needed. Initially I would prefer to have the lower cmc creatures on the battlefield allowing me to play faster. Thanks for the ideas though!

Yes i'll take a look at some of your decks here shortly.

I disagree with using a Wrath of God in the MD over the 4th Path to Exile. Unless your local meta is becoming overrun with CoCo decks, I'd put the Wrath back into the SB. Also, the chances of you ever activating your Emeria, The Sky Ruin in a game are next to none, and I don't think it's worth having a ETBT land. The goal of this deck is to win ASAP, not drag the game out to where you have 8 lands in play. Also I'd actually cut the number of Cavern of Souls down to 2, since they can't level up a Student of Warfare or cast your instants, but having access to 1-2 is still good against control. Your creatures look good, although I stopped using Kinsbaile Cavalier a while ago in favor of Elspeth, Knight-Errant. If small creature decks/CoCo decks continue to rise in popularity, I'd consider adding a Sword of Fire and Ice to your deck for additional removal/damage.

+1 for Knights!

@GeminiSpartanX Thanks for the info I see your point with switching Path to Exile and Wrath of God. I added Sword of Fire and Ice to the maybe board, I will use it if needed in the sideboard. I have actually been able to make use of Emeria, The Sky Ruin on several occasions and it is annoying as heck. I'll probably keep one in. I haven't yet encountered an issue with Cavern of Souls but your point is certainly worth taking note of. Elspeth, Knight-Errant is a very interesting idea, I may toy around with it. Thanks for the input, it was really helpful.
