Reach
When Bonny Pall, Clearcutter enters the battlefield, create Beau, a legendary blue Ox creature token with "This creature's power and toughness are each equal to the number of lands you control."
Whenever you attack, draw a card, then you may put a land card from your hand or graveyard onto the battlefield.

Beau's power and toughness change as the number of lands you control changes.

Putting a land card onto the battlefield with Bonny Pall's last ability doesn't count as playing a land. You can put a land card onto the battlefield even if you've already played your land for the turn.
