Rules Processing

This is an unofficial term, that refers to a step within the overall Effect Resolution Process. This page expands on the base provided by Triggered Effects, it is recommended to read that page before learning about Rules Processing.
Rules Processing typically occurs after effects have triggered (but not yet activated) from an action or another effect. It does not happen if an effect is currently in progress.
== Page Terminology ==
This page follows the same page terminology as Effect Resolution and Example Structure as Triggered Effects. As Rules Processing is a step within the Triggered Effects Resolution process.
==Procedure==
We know as Rules Processing the process by which the rules remove elements that should not exist in the battle area: 
*Send to the trash any Digimon with no DP in the Battle Area.
*Send to the trash any Option cards in the Battle Area (that were not placed in the Battle Area by an effect specifying to place it in the Battle Area)
*Deletes all Digimon with 0 DP.
Effects still follow the Triggered Effects procedure, Rules Processing is a step within that procedure:
# An effect has activated.
# Effects met their Trigger Condition from the previous effect trigger. 
# Rules Processing removes elements that should not exist in the Battle Area.
# Effects met their Trigger Condition from rules processing trigger.
# Players then proceed with Triggered Effects procedures again. 
This can continue indefinitely, until all effects have been triggered and activated.
