Just an fyi for those interested. Am a regular viewer and tonight they announced his appearance next week.
Oh you mean this kind of shark tank? I hope he's got a good shark suit and that shark cage thingie! (at 1:52)
I got to "meet" Mr. Rubin via Shark Tank this past Friday night. He got into it with Cuban briefly. But they did join together for a deal. Rubin made 2 deals. He only mentioned his acquisition of Topps briefly.So nothing was really learned card wise from his appearance.
