Ziaru, Lizardbane

Reach, Trample
Ziaru enters the battlefield with X +1/+1
counters on it.
At the beginning of your upkeep, double
the number of +1/+1 counters on Ziaru.
Ziaru had the lizard-manned ship caught
between his coils, and he roared at the reptilian crew.
The lizards just stared up at his great head in terror.
