I asked him to play a game with me fully expecting to be told no, mostly because everybody would then want to play him. It just so happened that he was around at a time where I could drop what I was doing and get on iso to play him at his convenience. The read I got from him was that he plays on Goko at night frequently and he certainly wouldn't mind games with anyone at that point, whether scheduled or not. Perhaps you can just ask when he'll be on and meet him there? I doubt he would mind playing everyone in the world on F.DS as long as it didn't cost him any extra time out of his life. It could only be a good thing to have his army of raving fanboys putting up videos gushing about how awesome Donald X. and his games are, right?
I'd say you have absolutely nothing to lose by shooting him a PM and asking when he'll be on next.
If the kingdom has Swindler in it, though, watch out. He's a BEAST with that card! Buy as many Crossroads as you want, you'll never see one in your hand!
