batriders
 

get batriders upgrade their armor twice and make sure to upgrade that liquid fire thingy and then just go and wreak havoc on ur enemies base =) i love doing this and it works like 90% of the time cuzz once you have destroyed the enemies main fortress or tree of eternity they cant make any units that will be efective unless the rebuild which gives you plenty of time to bring some melee in to finish them off:grin:
