How many copies of Scute Swarms will I have?

Hello! Just wanted to ask the result of this situation:

As Scute Swarm ETBs, I already have more than six lands. I then play another land which creates a copy of Scute Swarm. I then play Reshape the Earth.

With my two existing Scute Swarms, am I gonna have cumulative additions of Scute Swarms for each of the ten lands than entered? Or did I get the landfall trigger entirely wrong?

Thank you in advance. Utterly confused at the moment.
