See Challenge # 143.
Like many things, it seemed like a good idea in my head until I put it onto a card.

Oh, well done for using "elastic". I thought that was a great word, but would need some work to find a mechanic that fit it well.

I like the idea though. It could be like level-up, an instant with three different lines an costs, but sufficiently closely related it feels more like one card than a split card.

Thanks. :-)

I imagine it would do better with a frame treatment of some sort.
