Charlie, The Redeemer

Whenever a creature you control dies, you may
exile that card with a redemption counter on it.
When you do, create a token copy of that
creature, except it's an angel in addition
to its other types and has flying.
Charlie, Redemption Princess gets +1/+1
for each card exiled with redemption counters
on them.
"It'll be a happy day in Hell!"
