While there's no Dark Depths/Thespian's Stage combo in Modern, that won't stop brewers from looking for the next lands deck with cards like this one
The order of rares, uncommons, commons may be different
The thing that pushes this to a level above cards like Impulse for me is that you can put things back into your deck and that is something not many cards in magic allow for, certainly not in such a cheap and painless way as this (except of course Brainstorm...)
Overall, Bruna is the best Angel commander in MTG for players who value inevitability and sustained board presence
This effect is simple, clean, and doesnt turn into a brick in your hand
There are many, many more possible commanders that will work well with cycling
