first of all, tell your sister "niiiiiice..."
regarding OP,
im thinking it lacks defenses?
>shields because you might not readily have the nymph/antimatter/quanta to use
(maybe grav. shield for most FG's? though that'd mean another enchant)
>healing, pretty useful against poison, but you will want to skip those
>nightmare, it forces FG's to draw 1 by 1, and with eternity, something awesome happens
i'm not really good at FG deck building, so don't rely too much on this
