Rogue: Spellcaster Synchro (by pseudoscientist)

Deck Introduction
A dedicated Spellcaster strategy is difficult to craft, as perhaps the best Spellcasters in the format are "Arcanite Magician" and "Kycoo the Ghost Destroyer", the latter being more renown for its role in Stun strategies. To make the most use of "Arcanite Magician", "Deep Sea Diva" is used as a means of rapidly putting two Level 2 Tuners on the board in conjunction with Special Summon monsters ("Cyber Dragon" and "Oracle of the Sun") and "Instant Fusion". With the focus being Spellcaster monsters, the Deck also has access to an additional strategy: locking your opponent out of playing Spell Cards with "Secret Village of the Spellcasters"!

Deck Strategy
Use "Breaker the Magical Warrior" to strategically probe your opponent's board and remove threats that could disrupt your essential plays. If you manage to pre-emptively snipe a Set "Royal Oppression" or "Icarus Attack" before committing too many cards to the board, you will better be able to carry out your big play. Additionally, "Deep Sea Diva" plays around "Book of Moon" disruptions, since it will put two bodies on board, but to ensure your "Oracle of the Sun" isn't your only play into "Arcanite Magician" you should play several copies of "Instant Fusion"! These plays can easily leave you dead in the water if countered by "Torrential Tribute", therefore it is advised to play "My Body as a Shield" so as to counter both "Torrential Tribute" and and surprise "Royal Oppression" plays your opponent might make. If you're taking the play, set up the standard Spy-Descendant play so you can start removing threats on your next turn as well as deck thin. Remember, your next turn could justify using your "Gravekeeper's Descendant" with "Deep Sea Diva" to make a "Goyo Guardian" and apply pressure by stealing monsters to Synchro with. Additionally, the strategy has access to "Chaos Sorcerer" due to the powerful LIGHT monsters played! Finally, "Magical Dimension" offers you to trade monsters that would otherwise be lost to "Mirror Force" / "Dimensional Prison" / "Caius the Shadow Monarch" for a last ditch body while also offering optional non-targeting destruction of an opponent's monster (this cannot be stopped by "Stardust Dragon").

Strengths and Weaknesses
Spellcasters themselves don't have any support that allows them to recover cards from the Graveyard beyond "Exodius the Ultimate Forbidden Lord" (if you're looking for a chump blocker that can act as a substitute for "Pot of Avarice"), so once your monsters hit the Graveyard it's safe to assume you won't be seeing them again. This is why "Junk Synchron" is played, as a means of recovering a "Deep Sea Diva" for a comeback Synchro play if you have "Chaos Sorcerer", "Instant Fusion", or one of the Special Summon monsters in your hand. The deck's main weaknesses stem from this inability to utilize cards once they have hit the Graveyard (or been removed from play), which is why "Raigeki Break" / "Phoenix Wing Wind Blast" were not played. What this strategy has in terms of strengths is limited, so never get greedy unless you have all the right cards to push for game.
