Doesn't seem good at all.
Secret package is clunky and Cloud Prince is only reliable as a turn 8 play with the secret the same turn or if you happen to Arcane Mysteries. Mana cyclone makes no sense in a highlander deck, especially since your hand is going to be full so often and you're only running a single copy of apprentice so odds for that combo to go off are pretty slim. Missing key control cards like Blizzard and Rolling Fireball. And you're running Primordial Studies with literally only 1 spell that can benefit from spell damage....I guess 2 if you count Violet Spellwing.
Case of mixed identity between tempo/secret/highlander and you're falling short on all 3.
