Vow of Elenda

When Vow of Elenda enters the battlefield put X
+1/+1 counters on target creature then create X
1/1 white vampire creature tokens with lifelink,
where X is equal to the number of creatures that
died this turn.
Whenever a planeswalker loses loyalty counters gain one life for each loyalty counter lost.
"I vow to defend the Immortal Sun, for those not yet
found."
