See, the thing is that most people are of the opinion that those cards pretty much died over a year ago. Sure, you could still legally use them this, but . . . why even bother? They're mostly trash this season, and that's all most people will care about: THIS season.
I liked Holon's Castform back in the day. And Ray ex d, and Steven's Advice. Sadly, they became obsolete as soon as we got a decent number of DP sets. I won't miss them because of the rotation, I'll miss them because they are practically useless now (except Castform, but you'll rarely put more than one in a deck and still win anything that matters). I'm sure many, many people agree with me, too.
