Made a cycle out of Ionic Thrust's ability. I'm not fond of giving damage prevention or life gain to the white card of a cycle... too many white protection cards make white bad to play... but I can't really think of something more fitting. Putting X 1/1 creatures into play works well at sorcery speed... but the Mirrans shouldn't be using Ionic magic, so the creatures would end up being either g/w or w/u or colorless or every color, and confusing people about the themes of my set. Meh.

So here's the $64,000 question: Do I add the reminder text:

(For example, if you paid to cast this spell, you would gain 6 life.)

to help clue people into the fact that the they must paid to cast this spell counts, or do you think it's ugly and/or won't really give a clue to anyone?

Was Spiritual Visit or Promise of Bunrei confusing for using colourless tokens? I don't think so. I think that'd be good. (Whether it's suitable for common is another matter, given Goblin Offensive. But who knows how sunburst will play.)

Hmm... it's not really a confusion issue. I just can't think of what this colorless creature would be on a world where colored magic is intertwined. I'll come up with something, I'm sure.

This would be a very strong common... but WUBRG for 5 1/1s seems fine by me.

Switched it to colorless spirits while I think about this.

It's nicely flexible, that's for sure. I think most people will figure it out; but on a common, unless you need the space for flavourtext, I suggest the reminder.

Well. A 1/1 on turn 1 is fine but unexciting. Two 1/1s on turn 2 is Raise the Alarm at sorcery speed. Three on turn 3 is getting hard to do in limited, but in the same way as Spectral Procession was hard to do (in the other direction) and they had flying. 4 on turn 4 is Battle Screech, again with flying, and 5 on turn 5 is Ordered Migration, again with flying. So making nonflyers seems reasonable compensation for the flexibility.

I'm pretty sure Captain's Call makes three tokens common enough. Four and Five are the stretch. (Edit: Oh, technically, there's Gather the Townsfolk. It's situational... but so isn't wubrg?)

also, I just changed 'colorless' to the mindboggling 'Put a multicolored token creature into play...' because I find that solution to be funny. I doubt I'll keep it, but it makes me smile for now.

I like that. What colour is it? Can you be more specific? Is it more than one colour? Yes. Is it any of WURBG? No. Buhh..

As funny as it is, you can't define something as multicolor. Multicolor is an emergent property of having multiple colors, like CMC is an emergent property of mana cost. I think colorless tokens, while not being the mechanical implementation, can work fine flavorfully. Like the Eldrazi, they are equally in touch with all five colors.

Hm. But the rules on a card can override any rule. So if the card says "is multicolor" then it is (although it may need to say "is not colorless" as well).

It's a bit like non-standard integers, it implies the existence of extra colours without saying what they are :)

I don't know if it would be printed on a real card, but I think it's surprisingly unambiguous! :)

It's plenty ambiguous, because it flies in the face of a fundamental attribute of games like this: changes to the game state must be constructive, so that players have some possible way of knowing what the game state is.

For example, I put a Blessing of the Nephilim on one of the tokens. What are its power and toughness? Is it a legal target for the ability from Vagrant Plowbeast? Or, I tap Bloom Tender for mana, getting mana that's apparently of some heretofore-undiscovered colors, then pump all of that mana into another copy of this. How many tokens does it provide?

Ha! Yeah, I could have guess who would end up on what side of the argument. I'm just happy to see everyone arguing. ;)

I like the idea, but it can't stay even if it's legal. It's bound to seriously ruffle feathers the wrong way with some people. Great bonus idea for an un-set, though.

How about a 1/1 spirit of each colour paid? So (W)(U)(B) gets 3 1/1s - one white, one blue, one black.

Wordier, and still doesn't really solve the problem. All Glornican creatures are multicolored. I'm thinking the best way to deal with this is to just make all the creatures be Elementals with all colors. It's not what I want to do, but it's the only thing that doesn't fight the setting. We even have the already there reminder text to help smooth over player confusion with paying colors and creatures that are all colors.
