Kruphix's Insight and Vessel of Nascency can be used to fill hand while also throwing Dragon Breath, Dragon Scales, Dragon Shadow and Dragon Wings into the graveyard.
While building up the lands for Humbler of Mortals play Grim Guardian(s) along the other enchantments to weaken you opponent. Being a 1/4 Grim Guardian is a good blocker as well.
Try to get lands of different colors to get rid of the occasional Dragon enhancements you might draw. The deck has full playsets of Terramorphic Expanse and Evolving Wilds for that purpose.
The deck is fairly slow so Quiet Disrepair is primarily there for restoring some life but it can be used to get rid of an annoying enchantment when needed.
Rhystic Study is a very strong card on turn 3 as it will either slow down your opponent or it allows you to draw some extra cards.
Seal of Removal is used to remove single threads but it can also be used on your own creatures. For example Grim Guardian, Humbler of Mortals and a couple of Dragon enhancements can end the game if you return the Humbler to your hand, play it again and attach some Dragon enhancements into it.
The deck runs very few creatures so it has a single copy of Soul Stair Expedition in order to recover 2 creatures from your graveyard.
