Which race would you add to Heroes?

the chat isn't working... the race doesn't have limited counterattacks and can fly, but otherwise:
1. only flies
2. immunity to psychic spells - + two attacks
3. archer, no penalty in melee - destroys castle walls
4. no retaliatory attack - same as above
5. dive attack - chance to block enemy attack
6. both cast spells
7. mechanism - + 80% magic resistance!
