I tried making the Ghostrick archetype as fast as possible but it lacks heavily on first turn as it needs to set a monster to start any plays, Ghostrick Shot and Parallel Exceed are the best cards to see first turn as they allow you to start going into your xyz monsters first turn to add specific Ghostrick cards and establishing a board, going second is even more of a challenge to overcome as setting against your opponents board is likely to end poorly. Most of the Ghostrick traps are played at 1 copy mainly for the reason they will brick your hands and are only strong when you have established, however it shouldn't be an issue because almost all the xyz monsters for the Ghostrick archtype can get a Ghostrick card back when they are sent to the graveyard.
You can run mystic mine as a very strong option to control the board and allow you to set up your plays but it was not included in this deck list because I don't enjoy playing the card.
The side deck here is just to reflect cards that can be added instead of other cards in the main deck as they are all strong options.
