Why TB and why W145? Leviathan Dragooon SA165W2D (or SD if you hate W2D for some reason) is going to be a lot more effective than any other combo. Precession is going to be really important for a spin stealer and TB just doesn't have it.
For Attack you could do MSF Gryph Begirados (Behemoth) 100/105RF for a LTAC. Begirados is crazy effective against opponents taller itself, so it should do pretty well.
Defense is kind of iffy; you could do an RF-based Defense thing with MSF Leviathan Saramanda SA165RF.
SA165 should always be in Attack mode (the outer ring down).
