Interactions
How do Ground Collapse and Ojama King interact with Call of the Haunted for zone blocking?!
Ojama King would block zones and Ground Collapse is activated.
Ojama King blocks zones immediately without starting a chain. Ground Collapse only blocks zones when it resolves, so Call of the Haunted must be chained earlier (e.g., to Polymerization) to occupy a zone before it's blocked.
