Life and Limb + Maskwood Nexus + Emeria Angel

Life and Limb

Maskwood Nexus

Emeria Angel

How it works

1. Play any land from your hand.
2. The land enters the battlefield, triggering Emeria Angel, creating a 1/1 Bird creature token.
3. The Bird enters the battlefield as a Saproling due to Maskwood Nexus, which also causes it to be a Forest land due to Life and Limb.
4. Emeria Angel triggers, creating a 1/1 Bird creature token.
5. Repeat from step 3.
