Hi, here is my first squad:

Boba Fett (51)

Firespray-31 (39), Veteran Instincts (1), Seismic Charges (2), K4 Security Droid (3), Glitterstim (2), Slave-1 (0), Engine Upgrade (4)

Bossk (49)

YV-666 (35), Marksmanship (3), Outlaw Tech (2), Mercenary Copilot (2), Hound's Tooth (6), Maneuvering Fins (1)

How to improve it ?

I have access only to cards and ships from The Core, Most Wanted, Slave-1 and Hound's Tooth (soon, I haven't bought it yet) and I would like to use this squad on tournaments. Please help me to start with X-Wing
