Sherlock Holmes inspired archetype.

I've been in a bit of a creative funk lately so I made these to just have something made. If anyone sees any spelling or card text errors/sloppyness please tell me so I can amend it.

 

The Grand Logician

Level 6 LIGHT

Spellcaster/Effect

1000 ATK / 1000 DEF

(Quick Effect) During either player's Standby Phase or your Main Phase, you can reveal your hand to your opponent; If you revealed a "Deduction" Spell/Trap card Special Summon this card, then increase its ATK/DEF by the number of revealed "Deduction" Spell/Trap cards X 1000. During the End Phase, once per turn; Add as many "Deduction" Spell/Trap cards from your GY to your hand as possible.

Logician's Apprentice

Level 3 LIGHT

Spellcaster/Effect

800 ATK / 500 DEF

If you control a "Grand Logician" you can Special Summon this card from your hand. Once per turn, you can shuffle this card from your hand or Field into the Deck; Add 1 "Grand Logician" and 1 "Deduction" Spell/Trap card from your Deck to your hand. Each time a "Deduction" Spell/Trap card resolves, place one counter on this card. Once per turn (Quick Effect), you can remove 3 counters from this card; Activate 1 "Deduction" Spell from your hand, or set one "Deduction" Trap from your hand (it can be activated this turn if you control a "Logician" Monster)

Logician's Foil

Level 9 DARK

Spellcaster/Effect

2000 ATK / 1500 DEF

While you control a "Logician" Monster, you can Special Summon this card to your opponent's Field. While you control this card, you cannot activate Spell/Trap cards except for "Deduction" Spell/Trap cards. Once per turn, the turn player can activate this effect; Both players reveal their Decks and add one Spell card from their opponent's Deck to their hand (the player who controls this card must add a "Deduction" Spell card by this effect). 

Spell and Trap cards (written only):

Perfect Deduction

Quick-Play Spell

Declare 1 card name; Reveal either your opponent's Hand or Deck, then if a card with the declared name is in the revealed Hand or Deck your opponent sends it to the GY. You must control a "Logician" Monster to activate and resolve this effect.

Cautious Deduction

Spell

If you control a "Logician" Monster or no face-up cards and your opponent controls at least one face-down Spell/Trap card; Declare 1 card name, then your opponent reveals all of their face-down Spell/Trap cards and banishes face down any revealed cards with the declared name. Your opponent cannot activate Spell/Trap cards in response to this card's activation.

Flashy Deduction

Quick-Play Spell

While your opponent has 3 or more cards in their Hand and you control a "Logician" monster, discard 2 cards and declare 3 different card names; Your opponent reveals their Hand, then if your opponent revealed at least one card with each declared name your opponent banishes their hand and all cards they control.

Responsive Deduction

Counter Trap

When your opponent activates a card or effect declare 1 card name; Your opponent reveals their Hand, then if they revealed a card with the declared name, negate that activation and destroy that card. You must control a "Logician" monster to activate and resolve this effect.
