What happens when there's 2 showdowns at the same time in different battlefields and how the order timings of this resolves?

In Riftbound, only one Showdown can be active at any given time. If multiple Showdowns (or Combats) are triggered, they cannot happen simultaneously; one must fully resolve before another can begin.

Here is how the resolution and timing work when multiple Showdowns are pending:

1. The "Only One" Rule

As established by RiftJudge FAQs, the game state must be in a "Neutral Open State" to start a new Showdown. This means the chain must be empty, and there must be no ongoing Showdown or Combat.

• If a new Showdown is triggered while one is already in progress, the new one enters a pending/staged state and waits.
• Once the first Showdown finishes completely (including combat resolution, conquering, and all "after" triggers), the game returns to a Neutral Open State, and the next pending Showdown can then begin.

2. Determining Order

If multiple Battlefields become contested simultaneously (e.g., due to an effect that moves units to multiple locations), the turn player determines the order in which these events are processed.

According to Rule 456.1:

"If more than one Battlefield has Units controlled by opposing players at it at the same time, the Turn Player decides which Combat to resolve first."

3. Typical Resolution Sequence

When you have multiple Showdowns or Combats staged, the process follows this flow:

1. Staging: The player whose turn it is decides the order in which they wish to resolve the pending Showdowns/Combats.
2. Resolution of First Showdown:
   • The first chosen Showdown opens.
   • Players resolve the chain (if any).
   • Combat/Showdown steps resolve fully.
   • All cleanup tasks, triggers, and "conquer" effects from this specific Showdown must finish.
3. Return to Open State: Once the first Showdown is completely finished, the game returns to a Neutral Open State.
4. Initiation of Second Showdown: Only now can the second staged Showdown begin.

Important Note: If you are using effects that trigger a second Showdown during an ongoing one (such as moving a unit with an ability during combat), the game waits until the current Showdown is completely over before the second one is allowed to start.

This is my interpretation based on the Core Rules 456.1 and established community-verified RiftJudge FAQs (e.g., FAQ 216, 4273, 7567). No official rule exists that allows simultaneous Showdowns.
