High card means...
Let's use Mr. October, Reggie Jackson as our example. He has multiple cards. His "high" card ($10.13) is with Oakland. Reggie only has 2 cards that are usable with the theme, his NYY and CAL cards.
PHA/OAK has "dibs" on Reggie and if they want him, he MUST be on that owner's draft card, of course using only the 2 cards mentioned above.
If the PHA/OAK owner DOES NOT put Reggie on their draft list and he's available as a FA, he's fair game for any team he played for.
Got it?
