how about rewording this to
'Summon 3+N living shields that absorb damage from a single source. N is equal to the number of creatures in play.'?
that way it sticks a bit closer to the wording on hope.
This.
Life is better at getting creatures out than Death. Mitosis, cheap creatures, already-in-place focus on the field with Empathetic Bond. Bonewall has 7 shields and more with death effects. This has 3 | 5 and doesn't add any for one less quanta for summoning cost.
Seems balanced, but only just.
