Naga Myrmidon

When Naga Myrmidon enters the battlefield, put
a +1/+1 counter on target Naga you control.
When a creature dealt combat damage by Naga Myrmidon dies this turn, proliferate. (You choose
any number of permanents and/or players with
counters on them, then give each another counter of a
kind already there.)
Precious few Naga still feel any sentiment to their kin.
