I like this

I dig this as well. Let's put it in tentatively, as I think we'll have space for it.

Could be stapled to a demon or a Consul Advisor too?

It could be, but I think it makes the build around a little more unstable. I think this text alone is better on an Enchantment than with other text on a more vulnerable body.

If this were on a creature, I am not sure if the mana cost would be necessary. I'd rather the enchantment, but the effect is pretty flexible.

Gonna try this card in the next playtest

Yowowow. I tried to build around Furnace Celebration, and that was basically unusably bad. My initial impression is that this is rather too far in the opposite direction. I can see Modern decks using this with fetchlands, for example.

Presumably is is for Canisters. I wonder whether "an artifact" rather than "a permanent" would make this too narrow?

I think if it wants to work in limited it needs to be able to trigger on creatures, but being a rare that isn't mandatory. How do we feel about just going to "non-land"?

I think modern is currently too fast for this to see any play, and even if the meta changed, while this can be strong I doubt it breaks anything.

Been getting lots of positive feedback about this card
