I have against me Skarsnik, 4lvl shaman, two goblin boss, two night goblin hordes, black orc unit, two mangler squigs and two giants... I haven't played for a while and I'm so lost with our new things that I decided to ask some help. I wouldn't like to get wiped out... AGAIN.
Rippers and Salamanders will tear apart is infantry. Chameleons will down giants. Bastiladons are a cheap way to get a terror causing unit to panic off units outside of the generals bubble. If you can get rippers into his BSB, it's totally worth throwing a unit away and killing his BSB. Goblin armies have huge problems with leadership, so sniping the BSB magnifies that weakness. Against this army, ethereal slaan actually works. If you can take out fanatics (force terror tests, or pull them out with 50 point cohorts), the Lizardmen character section can table his army.
