Looking for some help modifying Calling all Angels Precon

[u/_imperi0us_]

Hey, I am pretty new to the game and haven't gone out and done much modifying on any decks quite yet, but I saw the Calling all Angels deck and picked it up. I wanted to modify it to bring in the pair of Gisela, the Broken Blade and Bruna, the Fading Light because they seem like a really cool pair to pull off. Does anyone have any suggestions for modifications I could make to the deck to incorporate them? It would be nice if it could have some level of consistency although I'm not sure if thats very possible without some level of tutor cards. Any suggestions would be appreciated!
