One of the voices in my head came up with a suggestion for a mythic troop.
Echidna - The snake-woman who became the mother of most Greek monsters.
Her mana could be all colors/30+ cost and her special would be that once cast, all remaining allied monsters mana filled, +(X) Life and maybe even an extra turn if there are (X) number of skulls/doom skulls at the time of casting.
This may not be a consideration for the geniuses that you are simply because I’m not the sharpest tool in the shed (which just makes me a tool) and I’m sure there are a bazillion things that I’m not taking into consideration but I figured that I would put it out there just in case.
Please forgive me if this is already a thing.
Have a great day and thanks for everything.
