Exploring for lost the Sentinels

Okay, so I'm a long time lurker, first time deck list poster. I've always found sentinels fascinating and wanted to find a way to build them. I've looked on here and tried a few lists, hut they always seemed clunky. So in my searches, and testing I've found this list has so far worked the best for me. Eventually I will replace some power stones with 2 more crests, though i digress.

The deck is fairly self explanatory, you want to draw as many sentinels as possible, reducing their cost, and increasing your power cap.
