Blackened Lifeworker

Fabricate 2 (When Blackened Lifeworker enters the battlefield under your control, either put two +1+/1 counters on Blackened Lifeworker or create two colourless 1/1 servo artifact creature tokens.)
Whenever you gain life, put a +1/+1 counter
on target creature you control.
Most creators use steel, iron or aluminium, yet I
mould with death and build with life.
