When the card has no counters left, it's destroyed, you gain 4,000 Life Points, and you play another "Schoolwork" Trap from your Deck (of which there is only this one)
Here's how it works: The chessboard Field Spell lets you Summon a Level 2 chess piece (a 'pawn') directly from your Extra Deck each turn, and place a chessman from the Extra Deck in your Spell & Trap Zone
Each spot on the grid has its own terrain and each type of card is strong or weak in different terrains
Special Guests debuted in 2023 with 24 cards, featuring rare and uncommon, unlike later releases
This allows for a slew of A/B combinations between Doctor and Companion, each with a potentially unique color identity and mechanical theme
The card will be distributed at the ONE PIECE CARD GAME booth (#607
