basicially, it's the boon cycle on a set of lands.

 

not sure on that Blue one, though...

I like this idea with those different usages of the charge counters a lot.

Nice work you did there - why not releasing full cards of it?
 

Sad that I am the first one to comment :(

I really wish this section got more use.

 

Anyway, the blue one seems stupidly good next to all the other ones. Especially since the black one doesn't add any mana and the white one has been done on other cards. IMO you can drop the boon cycle thing since it limits what you can do too much. Other than that I think this has a lot of potential as an idea. I might end up making my own at some point.
