Hey mate!
Looking like a solid deck, though I feel like don't run enough Auras to make use of Estrid's +2 ability.
Personally, I feel like Estrid is there to create value especially by untapping enchanted lands for extra mana. I would see if there are more enchantments that ramp by enchanting lands.
Also, how did
Starfield of Nyx perform for you so far? Since lands are also enchantments I really
fear running into an enchantment AoE with this card on the board.
