I would say, if you are going for a budget Exert deck, you should focus on more exert lords, as well as some more efficient exert creatures themselves. In addition, untap effects may be important. Cards like Glory-Bound Initiate, Khenra Scrapper, and even Glorybringer could make for a good aggro deck. I would personally drop blue and add white, as a Naya colored deck would go well here. Resolute Survivors, Vizier of the True, and Watchful Naga are some of my favourites. For untap effects, I would recommend Dauntless Aven, Prepare and the like, along with others.

Thanks for the input I will give it a try

since you added white, always watching may be a good addition to give all your creatures vigilance allowing exertion every turn, and the stat boost is also nice, also it curves really nicely with glory-bound initiate letting you attack with a 5/5 lifelink vigilance on turn 3 and every turn after, providing neither gets removed, though, always watching may be difficult to play on turn 3 in a 3 colour deck.

Thanks for the tip.
I have two of them, so I will see how it does my deck and go from there
