Very consistent deck with ways to search basically any cards and with the possibility of a free pot of greed like card.
Lyrilusc - Cobalt Sparrow can search any level 1 winged-beast monsters so if you need you can also have access to D.D. Crow; Where Are Thou? can help you search for effect veiller if you have all of your combo pieces in your hand.
Swallow's Nest can fix your normal summon summoning from your deck the correct starter for your plays.
Bird Strike is a weaker dark ruler no more but it is easily searchable from your deck ; feather storm is not seachable in the deck cut its an extra utility resource, you can replace it with 2 more bird strike and 1 extra Sanctuary.
The Side deck contains cards that i'm experimenting with, it could be anything for the current meta.
