Mira and the Nightingale

Whenever a land enters the battlefield:
• If it is a Plains, put a +1/+1 counter on Mira
and the Nightingale.
• If it is a Swamp, put a -1/-1 counter on up to
one creature those power is greater than Mira
and the Nightingale's power.
• If it is a Forest, you gain 1 life and draw a card.
Feud of the elven courts is nothing to their bond.
