Someone asked a question if you can stack lifelines, and the answer is YES!
As long as you haven't used it yet, and you are willing to pay for it, you can use it however you see fit.
So if I got dealt the spectacular 2019 Orioles, I could flip it to the 2019 Yankees for $3M then use a franchise wild card on my new team to get Ruth.
The same would apply if you shift a year. If I get dealt the 1992 Dodgers, I could shift it to 1993, then flip it to the 1993 Braves for $3M and get access to Maddux, I can even put a franchise wild card on top of that and grab off 1894 Hugh Duffy!
So many possibilities out there!
