EDIT: I decided to include more teams in this concept, although I won't commit to a specific number of them. Also, to cut down the amount of scrolling necessary, original concepts will be replaced by edited versions.
Team's completed:
AL WEST
Anaheim Angels
Oakland Athletics
Seattle Mariners
Portland Lumberjacks (Expansion)
Salt Lake Swarm (Expansion)
AL CENTRAL
Detroit Tigers
Indians Cleveland Tribe
Minnesota Twins
Chicago Whit
You've been helping me with these concepts from the very beginning, of course I can do Omaha instead.
However, the next team up will actually be the New Orleans Krewe of the newly-formed NL South. Using the purple, gold, and green, the team is named after Mardi Gras krewes. The logo features a fleur-de-lis (different from that of the Expos) with a jester hat and the face of a jester's mask.
