Actually, that WonderCard is likely VERY widespread now. I can't believe none of you would be using personal Nintendo Zones? Since you can just streetpass TONS of people worldwide constantly every day, that Event should be well-spread all over the world already (I don't have my game yet, it'll be bundled with SmashWiiU-JP, so can't test; and my secondary wifi is being grumpy lately). Of course, if you don't actually get out and DO any of that easy streetpassing, yeah, cheating could your only way. >_>
But, a WC editor would be novel. Mostly useless (since you already can get whatever you want, and import the proper WonderCards), but novel.
As to all those Cyber Editor comments: Seriously, GIVE THEM SOME TIME. They supported Smash 3DS within several days, it really won't be long for OR/AS. You're not going to die from not hacking your game to pieces on DAY ONE. Why don't you try enjoying the game that you (I assume... [stupid Gateway and your blatant theft support]) paid for. Or did you really only buy it so you could just cheat in the newest game, story and whatnot be trash to you?
