The Gedwey Ignasia is a magical symbol of some sort that is branded into one's hand the first time he or she touches a dragon. This enables a telepathic bond with the dragon, but causes some pain initially, however, it's not really red. It's definitely not black, and possibly could be white, but really, the main flavor is a mysterious magical symbol whose exact properties are unknown that binds a Dragon and a Rider.

Form of the Dragon is an interesting example. That's always justified as "Moat isn't red. But 'I turn into a dragon' is very very red. And ground creatures can't attack dragons." However, it's very much the exception. Most cards should be colour-pie-appropriate. "I turn into a dragon" is one where they decided the flavour was so much better in mono-red than in red-X that it was worth the colour pie break.

So: I don't know the Eragon series. What does "Gedwëy Ignasia" mean? What does it do? And crucially, what alignment with Magic's colours does it have? Could it be blue-black, or blue-red, or red, or white-red? If not, then what about it is so utterly, inescapably blue, far more so than any other colour, that it justifies one of these very rare, very controversial, major breaks of the colour pie?

Explain to us what this card is about, and whether it could be gold; and if not then what makes it so very, very blue.

It's necessary for the flavor. Magic has made some huge bleeds, like Form of the Dragon, Beast Within, and Chaos Warp.

So you're justifying the color break by calling it a bleed?

It's a color bleed, the wording worked before, I edited it but you're right it doesn't work now.

1. Destroying creatures isn't in blue's slice of the pie.
2. The creature will almost certainly have greater than 2 toughness when it's trigger occurs, since the Aura itself gives +5 to toughness.

Target player what two cards? :)

Seems rather worse than Skyshroud Falcon. And Courier Hawk. And Hovermyr and Zephyr Falcon and Bay Falcon. (Blue used to have a lot of small vigilant creatures, before Wizards realised that was making it indistinguishable from white.)

A changed-name reprint of Courier Hawk might make more sense here.

Oh cool, this is another P/T combination which hasn't been done? It's a bit swingy but seems appropriate :)

I don't think there are many artists on this site. Searching up fanart of a given property often works quite well, though. Browsing sites like deviantart and similar can generally supply a lot of a set's custom art needs.
