Yes there have been several that have returned for example: Magic Spell Incarnate returned twice (Exchange & EH), Red Wings (+the other 3 needed), Joker's Sickle, Joker's Cane - all returned once in EH, etc. etc...

As for materials that could only be obtained from Ranking rewards, there was a Platinum Maiden ticket exchange (last spring?), which featured Celestial Laurels among others. But the tickets could only be received by doing Premium Summon - so it was basicly a reward system for cash players.
