Any one know of a way to remove the troops that someone donated during the preparation phase? One of the clanmates donated lvl 3 giants to everyone when lvl 5 wizards were available.
A recent update added a little red minus button beside the troops in the war screen so you can get rid of them if you don't want them
There is no way to remove the troops, sadly.
However, you are able to change the message on your village requesting specific troops, but of course you aren't guaranteed to get them.
EDIT: Added a comment on the question post
Well, you can always just go to single player and drop those troops off.
