Myutant Ghoti post the Darkwing Blast Ghoti support. Solid Anti-Meta, no Dark or Light monsters for Bystials, Banish-okay for Tear and Floo, good end board with solid negates, powerful extra deck monsters.
Use Myutants to set up boards while banishing the Ghoti level 2s. Use Myutant negates and banishes to stop opponent plays, threaten Deep Beyond with Level 2s. Use ST-46 to search Cry for either pops with Synthesis, or negates with Ultimus (if available).
If Ixeep becomes available from either Distant Deepest Depths, Gold Sarc, or a Myutant/Snop Banish; use to start Ghoti plays. Most common: Ixeep + 2 > Arionpos > Zep > Askaan/Whale > Arionpos 1, Askaan/Whale 2 > Banish Ask or Destroy Whale, Grab Snopios from Arion (Banishing Arion) > Ask banish to special, Snopios to interrupt with remaining 2 Fish in grave.
Mist and Royal Decree personal preference, good for going against Labrynth or Eldlich. Arsenal/Mist + Royal Decree shut down most trap deck plays.
Spright Elf can summon both M-05 and either Ghoti level 2 during opponents turn. Can get the search from M-05, or the Synchros from Ghotis (only required to be special summoned during opponent's turn, do not have to be banished except Zep)
Chengying a staple in Ghoti, runs off the banishment well. Ruddy Rose to banish graveyards, can activate D. Shifter after. Synthesis + Level 2 GHoti makes End Punisher, after Myutant Mutant very little chance your opponent can out PEP. Cut Guoglim for other staple Extra monsters, shut as Knightmare Unicorn or Baronne.
Other side deck options; Dimensional Fissure (Anti-meta), Crossout Des (Imperm shuts down Myutant very hard, good to keep that from happening), Lancea (Evenly), Called By (Ash, Droll, etc.)
