Why don't Ikaros & Tomoki use more the Transport Cards to solve their problems? Even thought in the first episode, Ikaros used her cards to accord every single desire of Tomoki, bringing to what looks like the end of the world, then the use of those is reduced to 2 times (I may have forgotten one or two occurrence(s)).


Episode 2 : Not intentionnaly when Tomoki wishes to make Sohara's underwears fly away unless it is the underwear Tomoki wants;

Episode 4 : Sohara borrows a card from Ikaros to bring all the panties in Tomoki's house to explode, Tomoki should look at them or touch them.



Why didn't Tomoki use more those cards to grant him what he wished?
Even if you take apart the opportunity of destroying/neutralizing Chaos by a single wish, he could have used it in some similar issues of the one mentionned above. Just as an example :

In episode 9, Tomoki spots an erotic DVD at a booth, but cannot afford it because Ikaros broke some other item.

It would be logical from Tomoki to use a card to get this DVD.
Well, I think many can agree that SoraOto is a series which displays a comedy side and a serious side, and sometimes (many times actually) the comedic parts, like the first episode for example, serves, in the best case, for character development and, in the worst case, just for laughs. Most of the information thrown at us in the comedy parts aren't really used on the serious parts, especially when it comes to plot solving. I personally think it is just the author's decision NOT to do this.

Also, I think that at the end of episode one, Tomoki learned that he shouldn't use the cards for trivial stuff, especially after everything that happened in that first episode. Maybe that was actually the author stating why everything shouldn't be solved by a deus ex machina-like device.
