Hm. So this effectively taps for , and often more. I guess it might be okay by comparison with Greenweaver Druid? It's more normally green that gets to do this rather than red though.

Yes green normally gets extra mana production but every color has gotten cost reduction on and off over the years. Granted this would have to be part of a cycle, much like tribal cost reduction has been in the past.

I'm testing this in red to see where the base line for the cycle should be.

Seems quite pushed in red; in green I wouldn't bat an eye. The other colours I'd expect it to see cost a bit more; but don't see a major problem with it in white. Black might want an additional life cost or something? Blue... feels kinda wrong to get it globally - but if it was restricted to just instants and sorceries; again, would seem fine.

Ok I did some looking around on gatherer. The last time colors each got cheap cost reduction was a cycle of rare artifacts in Tempest. Ruby Medallion and friends.

If this cycle was rare would that help balance the fact that it's cost reduction for the color reguardless of type?

Technically, the last time each colour got cheap cost reduction for all its spells was the common Familiar cycle in Planeshift: Sunscape Familiar, Stormscape Familiar etc. It's just they were in adjacent colours. :)

Being rare wouldn't help, as rarity doesn't excuse colour pie violations except for a small handful of cases.

I don't actually mind "Red spells you cast cost less"; what's more out-of-pie is the ": Add " line, actually.

ok I can see that I'm ok with these guys just being color reduction.
