If you can, definitely magnetize the commander and crisis suits so you can eventually swap out the weapon load outs.
The Fusion Commander is very dangerous but generally will be taken out the moment he moves to take out a threat. If you simply like the Fusion Blades relic and can trade up against an opponents expensive model its fine, but in smaller games I've found commanders with Missile Pods or Cyclic Ion Blasters to provide a more consistent threat.
You could easily swap the TL on the Crisis for a Drone Controller, then swap shield for gun drones. This way they will put out a torrent of firepower when they land. The team goes from 24 shots to 56 with the following changes:
XV8 Crisis Battlesuits [15 PL, 210pts]
. Crisis Shas'ui: 2x Burst cannon, Drone controller
. Crisis Shas'ui: 3x Burst cannon
. Crisis Shas'vre: 3x Burst cannon
. 6x MV1 Gun Drone
you can always add back in the iridium if points allow or swap out the third Burst cannon for ATS if you don't like the looks of 3 weapons.
Lastly if you do mount Smart missiles on the Devilfish, keep in mind they are heavy weapons and will cause you to shoot at -1 if you move, but ignore cover and can shoot targets it can't see. Drones are cheaper and can be disembarked to join up with the Crisis suit blob to shield/benefit from the Drone Controller.
