They are both easy. Bird would always have enough mana so dont bother with the Winds. Slaanesh: use your cav to attack troops from behind then go back (move like a circle) then repeat. This way you would have like + 99999% dmg. This is one of the most fun faction. Army should be a bit cav focused. If you played LoL/Dota/Starcraft it would be easy for you (play your cav like you are playing as assasin character).
