Nice cycle. The power level is a bit high though. Did Talisman of Dominance really need this much of an upgrade? The normal rule of converting landmana artifacts is that the artifact costs 2: see Underground RiverTalisman of Dominance, Prismatic LensShimmering Grotto, etc. Following that principle, this cycle is better than the original duals, as they can cast iconically powerful spells as well...

Yeah power lever is a bit high, ive been wanting to lower it down but dont know how without making them bad, i think making them 3 mana makes them almost completely unplayable, the only way they can cost 3 is to make the sacrifice abilities cheaper, but in order to prevent monocolored decks from using that ability it would have to cost a minimum of 2 mana so its still weak, any thoughts on how to lower the power level on this cycle without making them unplayable?

Make the mana ability painful. That way it's not a strict upgrade on Talisman of Dominance, which has a painless generic mana ability in addition to the painful coloured one.

Hmm yeah that would work really well, since they wouldnt have an option to give colorless, they wouldnt be strictly better.

I agree 3 mana would be very bad. I really like the sac ability on mana stones - Mind Stone is fantastic for that reason. I think either Chris's suggestion of restoring the pain, or the Sky Diamond option of making them ETB tapped, would make them fairer while still very playable.

I'd go with the pain option to make them similar to the other Talismans without a painless generic option.
