Donut summons totems in her distant duende battle, then Carl's mobile anchors relocate the summons into Quan's separate fight.
Donut remains fifteen kilometers away and chooses deck combat against the duendes. Because she is out of range, the Royal Court cannot formally join Ren and Quan's card match.
Her active battle still permits totem summons. Anchors placed at the Capitol let those totems appear beside Carl even though their squad is not a participant in Quan's battle.
Carl expects this means Quan's snares cannot target them and his own totems do not need to defeat Quan's cards before attacking the crawler directly. Donut sends a combined Lazarus-Skylar summon and Jola before the system can patch the interaction.
Two separate card arenas linked by teleport anchors as summons cross from one battle into another.
The exploit gives Carl outside-deck firepower that attacks Quan under asymmetric rules.
