Hariki, Colossus of the Deep

Islandwalk, trample, ward {3}
Hariki enters the battlefield with a tide counter
on it. At the beginning of your upkeep, put a tide
counter on Hariki. As long as there is exactly one
tide counter on Hariki, it gets -2/-2. As long as
there are exactly three tide counters on Hariki, it
gets +2/+2 and "All lands are Islands in addition
to their other types." Whenever there are four or
more tide counters on Hariki, remove all tide
counters from it.
