Notes & Combos
This deck will be easier for Spright players to pick up than for Cyber Dragon players respectively.
Your endboard is Infinity, Elf, Sprind, IP, Double Cross, Iblee lock.
That's an omni, bounce, attach as material, and an extra deck lock loopable on the opponent's turn.
Do not extend unnecessarily into Iblee if it costs you Sprind + Double Cross.
If your opponent doesn't clear Iblee right away, Double Cross their Normal Summon. They probably need it to out the lock.
Use Gamma Burst, and Cat Shark to facilitate your OTKs.
If all you open is access to Core, and a Galaxy-Herz line; Sprind before Elf and use it as a material detach for Gigantic Spright to set up Elf, IP, Double Cross. You can then, Elf the Sprind back on your opponent's turn once they control a monster, then use Double Cross to attach that monster as a material and bring Sprind's bounce online.
If Elf gets banned in the future, this deck is still playable with just Sprind.
