I know this is late but if you go to the dino forest next to Gau's dad's house in WoR you can win Imp Halberds from tyranosaurs.
Go to the Coliseum and wager you Imp Halberd to Cat Hood to Merit Award to Rename Card to Marvel Shoes to Tintinabar to Exp Egg. That might be out of order but that's the general deal.
