Blight-mad Tracker

Devoid (This card has no color.)

Landfall — Whenever a land enters the battlefield under your control, put a blight counter on Blight-mad Tracker. Then, if it
has three or more blight counters, remove
those counters and put three +1/+1 counters
on it, then you may have it deal damage equal
to its power to target colored creature.
