Hi there!

I think there are probably many better choices(10x Multihitter, etc) to use a UR Mirror Maiden on than an ATK Debuffer.

Some reasons

1. You can actually get Herb Stolas(50% ATK Debuffer) in the EH if you can do Intermediate(IIRC) Elemental Hall panels(Getting 8 Gem Stolas and Evolving/Amalgating them), its not as good of course compared to the cards you listed but this might be decent enough and thus make it less needed/necessary to Mirror the ATK debuffers you listed? Something for consideration that is.

2. Not sure what is your plan for your LAW team though, these days, the LAW Meta kind of revolve around Buffing enough Damage and then awoken bursting a Multihitter to kill the LAW quickly rather than trying to last as long as possible in the fight against the LAW.

In a debuffer LAW team, the longer a fight drags, the more Skill Nullify (Non-Attack) *Can't use Full Nullify since the nullify will be wasted on the Legendary Hammer* you need against the LAW's Legendary Domain skill. Question is, is there enough nullify in the team?

Or we could be turnskipping all the way with our LAW team(With the debuffer in it) in which case the debuffer's skill won't be that fully utilized anyway and we might as well use a Full Turn Skip + Unleashers Team instead.

Well, these are just my input for references. Decision still ultimately up to you :)
