It is best to limit non-Fairy, non-Hero cards in the deck and as a size 0 with worse stats than Kitty, Sylph will just get in the way. Just play enough items in the deck itself.

And I really do dislike Excalibur in the deck. You're trying to get both 10 Fairy and 10 Hero in drop? I would just pick one to focus on for the sake of consistency. Run extra copies of various combo pieces instead. He who tries to catch two hares will catch neither.

But yes to both Symbel and Breathen Gard. They may not be either attribute but they are useful and don't get in the way.
