Stephen the Martyr

When Stephen dies, put X 1/1 white Christian
tokens with "Sacrifice: put a +1/+1 counter on
target creature" onto the battlefield, where X is
the number of creature cards in your graveyard.
"While they were stoning him, Stephen prayed, 'Lord
Jesus, receive my spirit.' Then he fell on his knees and
cried out, 'Lord, do not hold this sin against them.'
When he had said this, he fell asleep." Acts 7:59-60
