Looking for an iPad app that can do what Microsoft Paint can do

Paintscreen_medium

I'm not looking for anything fancy. Just would like to copy & paste. Draw on top of pictures and be able to have a "fill" button so I can fill an empty space with a certain color.

Whenever I search for an app I can only find a $1.99 app that can only do one of the things I'm looking for.

Anyone have any suggestions?
