Multiplayer Movement and Response Order

Suppose A controls the newest finalized spell (its choices, costs and legality check are complete). A has Priority and passes to B. B passes to C. If C also passes, that item resolves. If C instead adds a legal Reaction, the new item waits above A’s spell and a new complete sequence of passes is required.

After that response resolves, if A’s spell is again the newest confirmed item, A gets Priority. A, B and C must all have their response opportunity again before it resolves. Earlier passes did not commit a player to pass on every later item.

In War, the same process includes D. A → B → C is not enough to resolve an item while D still has a response opportunity. Everyone must pass in sequence without another item being added.

Showdown Focus also circulates in turn order. A player with Focus may make a legally timed play or pass. A complete uninterrupted round of Focus passes closes the Showdown. When a chain started by an ordinary Showdown play empties, Focus normally advances; a chain opened by triggered abilities or an Add ability (one that produces energy or power) has the specific exception and does not advance Focus merely because it emptied.

All players may have relevant triggered abilities (created when their stated event happens), although exactly two opposing players participate in combat. Place the attacker’s combat-start triggers first, then the non-defenders’ in turn order, then the defender’s last. A player orders their own simultaneous triggers.

Example - A attacks C in War For the triggers generated by establishing attacker and defender, place A’s first, B’s then D’s, and C’s last. C’s are newest and therefore resolve first after their choices, costs and legality checks are complete and all required players pass. This placement order is not simply A → B → C → D.

A combat is staged when units of two opposing players are present but combat has not started its steps. The entry restriction already applies then. C cannot move or choose to play a unit into A and B’s staged fight, just as C cannot join their ongoing combat. A legal spell affecting the fight is different from adding C’s unit there.

If an effect requires moving C’s unit into that invalid destination, the unit is Recalled instead. If an effect requires playing C’s unit there, play it to C’s Base instead. Subsequent “here” in that corresponding play effect refers to the Base. Forced Move and forced play have different outcomes; neither adds a third combatant.

Effects may create contests at several battlefields. Only one Showdown or combat runs at a time; the turn player chooses which staged combat to resolve first. A staged fight that loses its opposing presence before its steps begin is no longer resolved as that fight.

Example - A second battlefield changes A and B are in an ongoing combat at the left battlefield. A legal effect moves one of A’s other units into C’s presence at the right, staging an A-versus-C combat. It waits while the first finishes. If one side leaves the right before its combat begins, do not run an obsolete staged fight. Ordinary Standard Moves cannot be issued during a Showdown or combat; use an actual effect with the required permissions.

In Magma Chamber, your units cannot move to a battlefield occupied by your teammate’s units. This applies to instructed movement as well as Standard Moves; an instructed invalid move becomes Recall. It is separate from the rule excluding a third participant from a staged or ongoing combat.

Before announcing a play, check timing, target choices, movement destinations and who already has units at each destination. Being a teammate or having Reaction never removes those destination restrictions by itself.
