Elder Berry

If Elder Berry is your commander, you may have
up to two of each other Berry card in your deck.
At the beginning of combat, if you are attacking,
reveal the top X cards of your library, where X is
the number of Berries you control. Place any
Berries revealed this way onto the battlefield, and
put the rest on the bottom of your library.
If you have 5 other Berries on your battlefield,
transform Elder Berry.
