Notes & Combos
Pretty basic deck, but I'll go through it anyways.
Of course you need the Spright, Nimble and Frog package to facilitate the sprights. As for fiendsmith, you almost always go into Caesar since it gives you an extra link-2 on board for your plays (I was almost considering cutting desirae because of how much more I went into Caesar).
As for specifics, Spright Smashers is cuttable and you can do whatever non-engine you want, I just like droplet and an extra target for Jet. Nib is interesting because its a great card that came up a lot, but you're locked out of it if you use Starter on opponent's turn, which might not be optimal. The 2x Gigantic and Sprelf are very necessary as well if you go beyond turn 2. You could also cut Underworld Goddess, but I actually really liked using her since not only is she a board breaker, she can be linked off into Requiem for Fiendsmith.
Other options you can include and why I didn't:
Mannequin Cat: One of my favourite cards, but it rarely ever came up. You already have enough to do with 2 bodies, like Fiendsmith.
Fiendsmith Agnumday: Actually could be great for this deck, but I went into Caesar more than Desirae so it wouldn't have come up much. Helps OTK though, which this deck could have some issues with.
Necroquip Princess: Could be good for insulating against Nib early if you start with Fiendsmith combo, but I didn't have the dust to craft her and going into Caesar with Sequence/Lacrima nets you an extra link-2 body.
Accesscode Talker: Could work here as well, since it solves two issues with this deck, that being the lack of access to removal (partially why I run Smashers) and struggling to OTK. I just preferred Underworld Goddess as a board breaker (also has synergy with I:P).
Mulcharmy Fuwalos: Don't have dust.
