This is the only Blue contest in my book as the others are too lopsided.
Rachael can band to Jacob (which makes playing RTC not susceptible to CM or UW).
Rachael can exchange for Joe or Ben (and their CBN awesomeness).
Rachael makes Simeon's SA work (to take out the little defense an opponent has).
Jacob can band to CotH (for FBN awesomeness).
Jacob can play RTC (for pre-block ignore walkins).
I think I gotta go with Rachael actually.
