Grove Frog

Leap 2 (Whenever this creature enters the battlefield
or attacks, you may exile the top X cards of your
library. If you do, put a +1/+1 counter on this
creature for each land card exiled this way.)
Whenever a land enters the battlefield under
your control, put a +1/+1 counter on Grove
Frog. As long as Grove Frog has five or more
+1/+1 counters on this creature, it has hexproof.
Groovy Grove Frog grooves with nature.
