Geralla River Giant

Whenever one or more counters of a single type are placed on Geralla River Giant, put a counter
of that type on target creature you control. Until end of turn, that creature can't be blocked by creatures with power less than the number of counters on Geralla River Giant.
The gentle giants of the rivers won't attack you and your boat. Just pay attention because if you unintentionally drift into one's mouth....
