Others have already pointed out good abilities. I'll mention Requiem Angel. When a non-spirit dies, you put a 1/1 spirit token into play instead. Except that effect is replaced by creating a 4/4 flying angel token. Since it's not a spirit, when it dies Requiem Angel's ability will trigger and put a new 4/4 angel on in it's place.

With Teysa out in addition to these cards, each time an angel dies it creates two more angels.

Others have already pointed out good abilities. I'll mention Requiem Angel, which states:

When a non-spirit dies, you put a 1/1 spirit token into play instead.

When your Divine Visitation is on the battlefield, this effect is replaced by creating a 4/4 flying angel token instead. Since it's not a spirit, when that creature dies, Requiem Angel's ability will trigger and create a new 4/4 angel in its place.

With Teysa Karlov out in addition to these cards, each time an angel dies your board creates two more angels.
