Well, I screwed myself over not knowing we needed Legendary Fisherman later in the game. Now I am stuck at level 48 because I got ride of Fisherman and always trying to get more blue keys to farm Mako.
Hey! I Also Sold It, Useless Card... Don't Worry, Just Duel Mako Level 40 And Use The Exchange Card To Steal His Legendary Fishermen So That You Can Use Them, It Still Counts
I have 2, I can help you if we can talk on chat while having the duel, using my 2 Fishermans, Exchange and that one card to get a monster from Graveyard, if you want help, just tell me.
