Hello stroodl, thanks vewing and for your recommendation.
I considered
angel of the dawn but it has a very high CMC, in this case 5. I've pretended to keep the curve of the deck bellow 2. I finally decided to give the finisher paper to the angel of dawn,
lifelink is really necessary. Another good card to consider is
tormented angel.
It's hard to find powerful angels in pauper ...
Regards!
