17-1-2Rule checks aren't performed in the following situations.
17-1-2-1Rule checks aren't performed during rule processing. (Examples: If an immediate-type effect activates during rule check processing and a Digimon is played, a rule check won't yet be performed for that Digimon even if it has 0 DP. A rule check will only be performed after the previous rule check is resolved. If the Digimon has 0 DP upon the new rule check, it will then be deleted.

(Example: If an effect reads "[On Play] [When Digivolving] 1 of your opponent's Digimon gets -3000 DP and <Security Attack -1> until the end of their turn," a Digimon whose DP becomes 0 due to getting -3000 DP will be deleted upon a rule check after it gains <Security A. -1>.)
