With the collection screen characters growing, it would be nice to see an additional sub category join "ability dust and creatures".
Most useful would be a teams category. This would offer two or three team slots, each containing 4 creatures slots of each colour. Additional team slots could be purchased. Clicking on a team slot of would allow you to set and re-set your creatures.
I would position this below the creatures section, as well as the dust section.
I'm sure this gets across the basic idea, a few tweaks and I can really see this being a great addition.
