You shouldnt put all your eggs in one basket, Super Combatants or otherwise. But that doesnt mean that SCs arent valuable just because the enemy has assassination spells.

IMO, I would always kit out an SC over summoning a new one. With the exception of a chasis that had strong intrinsic magic that I could use to buff them thoroughly or cast some particular spell to support my army. Another concern would be unique SCs. In that case, I would always want to immediately summon more of them -- to lock out that whole class of summons before my enemies could get any.
