How to Farm Bronk Stone

Strategy

• Can be run Skill-less. Skills that can be run include Spell Counter Boost , Call of the Magician Girls , My Monster Cards , Draw Sense: LIGHT , Draw Sense: FIRE , Draw Sense: EARTH , and LP Boost Alpha
• Your ideal opening is to either summon Loading... (searching Chocolate) or Loading... (Discarding Berry to Draw a card), otherwise you want to attempt to stall with either Loading... or Loading...
• Your Goal is to get 2 Loading... on the field (by using the effects of Berry, Chocolate, and/or Apple) in order to draw through your deck with their effects.
• When applicable, use the redirection effects of your Magician Girls to protect the Chocolate Magician Girls, otherwise draw through your Deck as much as possible with Loading... and Loading... (Make sure you pass each turn with either 2 Chocolate Magician Girl or 1 Chocolate with a Berry in Graveyard and another Chocolate in Deck if possible)

Last Turn

• Note that the final Turn doesn't necessarily need to occur when you're out of cards, if you have the means to Xyz Summon a Rank 4 and Loading... with over 10k ATK, that can make up for any Duel Assesment you would be missing (your mileage may vary, of course).
• If Bronk has Loading... out, Xyz Summon Loading... and use its effect to Destroy it. Otherwise Xyz Summon your Loading... (As it's guaranteed Prismatic), Loading... (As it's a Spellcaster you can use Loading... on), or Loading... (if you have two Loading... , and get the bonus Duel Assessment for Xyz Summoning.
• Activate Loading... to Fusion Summon Loading... with 5 differently-named Spellcasters and use its effect to wipe the Field.
• Activate both Loading... on Quintet and Attack Directly for Victory
