For the first squad, you would want to use the strongest units available to deal as much damage as possible. Of course, you are able to sub in three of the units in that squad, but double Cardes leads and Tilith are a must. In Trials, I tend to sub Shida for Exvehl so I can cure my status ailments. However, in future Trials, Alim might add more bosses that cancel Leader Skills. Trial 005 is a good example of this.

For the second squad, it is much harder to construct due to the fact that Tilith leads are insanely scarce. Getting Tilith leads with the right spheres equipped is another problem that factors in. Eventually, everyone will get a Tilith since she's a free unit, but it's a long stretch to obtain her and not everyone is going to use her, especially as a Lead.
