How does this fare in this scenario :

Opponent has Four of Tamayorihime, Brave and Bold, along with the TD cross SIGNI (4/3 cross) on the field. Since both are crossed, they end up with a 20k L4 SIGNI and a 13K L3 SIGNI on their field. You use this, and drain them both by 15k, effectively banishing the L3 SIGNI. Since they're no longer crossed, the L4 SIGNI's power drops to 12k (-5k since it's no longer crossed, and -3k since the cross constant is no longer in place due to the absence of the mate.). Does the L4 get banished, and why/why not?
