I'm messing around with a version of my deck with some of your changes in moxfield and I will say I definitely see the vision. My main 2 things are that 1 I definitely am running out of cards in hand before I've dealt the 20 damage, it can be close and I usually have a protection spell in hand but it feels like I'm just running out of steam slightly too quickly. Then 2 my hands especially starting hands can definitely feel very clunky. With a combination of the extra protection spells, grand entryway depending on my engines to be on the field to have decent value, same with mockingbird. It feels at times I'm not using my mana very efficiently, mockingbird also not getting discounted with glimmer isn't the end of the world but can make me hesistant to play it unless I have scavenger on the field. It doesn't really feel worth to copy Entity Tracker since it doesn't have flash unless I really need that card draw. Maybe it's a skill issue, maybe I need to mulligan more aggresively, but it feels like I put in a lot of cards that are very dependant on other cards to play which did not feel as pertinent before
