I love gold cards and all, but isn't this just going crazy with it? I always wanted them brought back, but not so in-your-face.
Imagine it's Thanksgiving. You get to nana's house and she asks you what you're most looking forward to at the big meal. You tell her, she nods and then when it's time to eat, she force feeds you what you asked for until you can't stomach any more. Then she gives you another 2 helpings on top of that because hey, you asked for it right?
That's what R&D's design philosophy has been like for a while now.
"I like tribal!" Here, have Onslaught Block. Oh wait, you still wanted more? Here's Lorwyn.
"I like artifacts!" Here, have one of the stupidest sets ever. (Mirrodin)
"I like legends!" Here, have a whole mediocre set of them. (Kamigawa)
"I liked Invasion Block!" Here, have Ravnica. Oh wait, you still want more? Take Alara Block too. I worry you don't eat enough, honey.
edit: I just sort of got back into the game and I'm already bitching about MaRo's merry band. It's good to be back, baby.
