I had an idea for 2 cards called Red Shift and Blue shift. No idea about the artwork but essentally the cards generate a
for every
(Red shift) or a
for every
(Blue Shift). They are permanents. this may be a bit overpowered so i think maybe one
or
for 2
but i don't know. essentally the idea is to make light easier to use as a multi-color becase it isn't very good on its own (at least not pvp). The card cost is ~5 and upgrading it makes it immaterial.
