I'm really confused with Frozen Spire E4

In this level, there are 1 cloud, 2 winds given.

From what I can see, the cloud have to be used on the hole right before purple button to allow user one time pass.

That left with 2 winds for the remaining two. To get the green button, I have to send 1 cloud in, then it would stuck there. The brown pillar requires two clouds together to get the box on. So regardless how I do it, I need one extra cloud

What am I missing here?

Your initial assumption about how to use the cloud isn't correct. There's a way to push the crate onto the purple button without permanently using up any of your resources.

Shove an Air Elemental into the area with the purple button before heading in yourself.

Thanks! i'm able to not use the cloud and get the purple button.

Edit: after looking at it again in a new day, I finally got it!
