Is there still a tie possible in combat? If so, how does it work with Symbol of the Solari?

Yes, a tie in combat is still possible. According to the updated rules for the Resolution Step of combat, a tie occurs if, after the Combat Damage Step, both players have units remaining at the battlefield.

Here is how it works with Symbol of the Solari:

1. The Tie Condition

A tie is calculated after the Combat Damage Step. If both the attacker and the defender still have units present at the battlefield, the combat is considered to have ended in a tie.

2. Symbol of the Solari Trigger

When this tie condition is met, Symbol of the Solari triggers its ability.

• The effect is placed on the chain.
• Once it resolves, it mandates that ALL units at that battlefield be recalled to their controller's base.

3. Interaction with Combat Resolution

Normally, in a tie, the standard resolution procedure (as per the Spiritforged updates and RiftJudge FAQ #2029) is that only the attacker's units are recalled, leaving the defender's units at the battlefield.

However, because Symbol of the Solari explicitly states "recall ALL units," it overrides the standard procedure for the tie result. When the ability resolves:

1. Both the attacker's units and the defender's units are recalled to their respective bases.
2. Because units were recalled during the Combat Cleanup (or as a result of this trigger in that window) and no units remain at the battlefield, the combat result is officially declared as "No Result" (per Rule 461.3.d).
3. Because there is "No Result," neither player conquers the battlefield.

Important Note on Recall: As clarified in RiftJudge FAQ #9850, units do not exhaust when recalled due to a tie; they retain their current ready or exhausted state upon returning to their controller's base.
