What happens if a new showdown is triggered while another showdown is already in progress?

Ruling: When a new showdown would start during another showdown, it enters a "Staged" state and waits until the first showdown ends before starting.

Sequence:

• First showdown proceeds normally
• New showdown enters Staged state
• After first showdown ends, the Staged showdown begins
• If multiple showdowns are Staged simultaneously, the active player chooses which starts first

Nuances:

• This situation is very unlikely in 1v1 games
• More likely to occur in 3+ player games where there are multiple battlefields
