For purposes of this theme, do we consider Mil-Exp as an NL team, which they have been since '98, or an AL team, which they were from '69-'97? Or do we just go on a card by card basis? In other words, I could put T. Higuera's '88 card on my '76-'93 AL team, because that card played in the AL, but the '09 Fielder card would be available to the '94 and up NL owner. :?
Also, am I correct in assuming that, in the case of players with multiple cards spanning two eras, we are confined to only using the cards that are specific to our particular era? In other words, I could not use Ripken's '99 card on my '76-'93 AL squad.
