The use of spells and commands (in the case of the Command Deck) was kind of poorly implemented in games in that some are just stupidly over used and can end fights in a second. In KH:3D, you had Balloon/ra/ga. For me, BBS had magnet/ra/ga because you could just round up all the enemies and just attack them as a single unit while the spell does damage independent from that.
Lol, and for Re:Com: Just basically every late game spell.
