Substitute Aldo for Ottavia & Don for Vickie.
Concerning your other query, If all the above mentioned Montanas are at their highest LvLs, you have 10 stars to spare on the rest 4 cards. If you want to play offensive or counter-attacking, choose the Uppers, Ulu Watu or Bangers. If you're defensive, go for the Sakrohm.
So ...this means that the clan that is combined with the montana is going to be slightly weaker.
Are there any other clans that would be suitable for this montana combo?
