Locking teams & costumes!

Dear all, I hope i can find support from all friends here and that this topic can become live soon! As you all know, costumes cannot be locked in teams, Nowadays costume heroes are countless. It happens to set a great Defense in tournament or war, and then go raid and change some costumes accordingly, then you just forget to put back your tournament or war team and boom, the initial team is destroyed!! that’s really annoying and affecting badly! My proposal is to simply Lock all teams. for example i have Costume MN in my buff tournament and the same card but regular MN in my war equalizer Defense. They just need to be locked. that’s my proposal. If not locked, one of the battles will be badly affected. Please look at this matter to lock costumes in regular team caps/ war/ tournaments. Thank you!!

Great idea! This would be very helpful
