That is, a spell that costs , or . A creature costing , for example, should make sense as a creature, a creature, a creature, and a creature simultaneously.

It could also potentially cost , I suppose.

I created Adept Vanguard and Soul Slash.

Oddly, I had a game plan for when I needed to make 4 color cards. My plan was originally for cards colored , but I can adapt. The non-creature spell will probably be trickier, since I didn't have anything planned, but until I design that, enjoy Community.

Hmmm... this is ebil; since all the colours share some overlap. Easiest way is probably just to slap a bigass pile of keywords; or use the horrible "If U was used to pay for this, then.." formula. Will have a thinky.

­Deathstalker Scorpion and Ing Charm

Got there. Knowledge Dump.

Created Selkie Soulbreather. Musing more about what bugs me about unrelated hybrid symbols led me to create Anthem of Progress.

Did you intend for it to be legal to do something like Phyrarion if the Phyrexian symbols were changed to 0/C hybrid symbols?

No, I don't count Phyrexian symbols as hybrid.

Although I guess the terms of the challenge do permit something with cost ...

Huh. You're right.

I hope I'm not too late
