Thanks @bitcoinflood. I have a feeling Elemental Foods are going to be really important too. One of the things I learnt from Prospectors was that there was early demand for construction materials but once the early construction phase was over it was the consumables that were the ongoing source of profit.

I do think the Splinterlands team are smarter with their designs, but am still wary enough to want to make the longer term profit play with consumables.
