Im a veteran player but have never run an escalation build. I will be entering an escalation tournament in early march that is four rounds 60-90-120-150

i typically like to run rebels with a Y and/or Hwk for support. also like to throw in a Bwing.

the thing is i have never run this format...ever. Ive only done 100 point lists. what is a basic, successful philosophy for this format? should i start with a couple of scrubs then build my main pilots? help!
