Rearrange fight, replacing Charlie with Henry (7)
I believe the answer is:
shuffle
'rearrange' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for shuffle that I've seen before include "Act evasively" , "dance" , "that dealer's used to?" , "Rearrange (card pack)" , "Reorganise playing cards" .)
