Does Targon Battlefield start a chain at the end of turn that can be reacted to with Shen or other reactions?

Ruling: Targon Battlefield does not create a trigger at the end of turn. It triggers only when you conquer, and the "at the end of turn" portion is timing for when the effect resolves, not a trigger condition.

Sequence:

• Targon Battlefield triggers when you conquer
• A chain is started once the conquer resolves
• You choose the runes to ready at the end of turn, but this does not create a new chain

Nuances:

• The wording "at the end of turn" appears at the end of the sentence, which indicates timing rather than a trigger condition
• There are currently no delayed triggers in Riftbound
• Common end of turn triggers that do create chains include Sona and Annie Legend
