Pebble, the Ever-Growing

Landfall —Whenever a land enters the
battlefield under your control, choose one.
If that land is a forest, choose two instead. You
may choose the same mode more than once —
• Create a 0/1 green plant creature token.
• Put a +1/+1 counter on Pebble, the
Ever-Growing.
• Remove two +1/+1 counters from Pebble: Put
a +1/+1 counter on each plant creature you
control.
