In theory, 4 wizards with 1 Sky Drake each and 1 wizard with 4 Sky Drakes is the same thing. Why would I consider the number of wizards?
(yes, I know it's just in theory, in reality they'll probably have lower tier units if the total power is spread around, but also 4 wizards using curses and spell blasts is several times as painful as one even if they are 1/4 as powerful individually so there are effects that change it in both directions.)
