1. Play a low bid list with high activations and 2 MC30s.
2. Learn how to have both MC30s targeting the same ship, 1 before and 1 after target activation, using all of above advice and thinking in terms of threat area: how can I position so that I can threaten best an incoming ship and profit from activation order. Threatening the right area leads to either cold hard damage or an enemy ship being redirected into a suboptimal position.
3. Remove the 1st MC30 from the equation: this is how you play a mc30 as 2nd player, or as 1st player when you want to get really close to what demolisher can offer.
Also, nav dials all the way.
