About the UI, I would prefere to keep in the Canvas, as it's good, powerful and the best tech atm.
@nensuru: Woah another dissapeared reappearing! Good to see your avatar again.
I don't think AT ALL that the cards added should be biased by the winners of tourneys. It must be a balanced and fun card proposed by the devs or anyone in the community, no more conditions. After that, all what's needed is someone who knows how to program it.
@SethKips: I'm not a fan of the squared spots, maybe it can be done with hexagons like 1.4? You just need 3 coordinates for each spot. Also, marking the centre of the map is quite odd. Thoughts?
