When the land enters the battlefield, each Scute Swarm you control triggers.
Resolve the first trigger, creating either a 1/1 Insect creature token or a token copy of Scute Swarm.
When the creature token enters the battlefield as a 1/1 Saproling that is also a Forest land due to Life and Limb and Conspiracy, each Scute Swarm you control triggers.
Repeat from step 3.
NOTE: This combo creates an infinite mandatory loop that will draw the game if it is not interacted with.
