I have at my disposal:
8 termagants
8 Hormagaunts (please advise if to give AG or TS)
8 'stealers with EC
2 Gargoyles
1 ripper swarm
*= not constructed yet

I want to make a 500 pt. list, so I can mulch my friends necrons.
Where can I get RC for my raverner?
Should I get a Hive tyrant or warriors for extra synapse?
Please give advice on Hormas, Broodlord, 'stealers and Zoanthrope.
