Gargoyle of the Sanctuary
EARTH - Level 4 - Fiend/Effect - 2000 ATK/1100 DEF
If the turn player adds a card(s) from their Deck to their hand, except by drawing them during the Draw Phase, for the rest of the turn, neither player can add a card(s) from their Deck to their hand. If this card attacks, negate its effect until the end of your opponent’s next turn.
If you don't know, Protector of the Sanctuary is a peculiarly old card that just says no drawing outside of the Draw Phase. Usually, that's used with Disturbance Strategy, where it reload's your opponent's hand, but then don't because they can't draw cards so they end of with an empty hand. Protector of the Sanctuary is also an EARTH Fiend, so then I thought Gargoyles and then I thought of the second effect.
This card can be used a couple ways. It can be a 2000 ATK beatstick if you want it, or stun your opponent's Deck thinning if you need it. Not much else to say other than that this card might be enough to mainstream Disturbance Strategy if it was released.
EDIT: Made the card not be able to use Disturbance Strategy until they actually add a card to their hand. It's also a bit less punishing if you Special Summon it in response to a search.
