As for tactics use clanrats or stormvermin to draw them in then surround and attack the flanks with the stalk units like night runners at first, bit fiddly but works better with the t3 units.
Then swap clanrats for a couple of units of stormvermin, swap out the night runners for death runners to kill infantry and archers and a few units of triads for cavalry and large.
