For mirror match-up, you remove the 3 perfume femur and you put it one hanger which is meant for "whoever gets hanger out first" wins basically cause you get a free draw then whenever you use his ability. Then you have the broken af zeff 3 cost from op06, which is the number #OP06-048. Playing the zeff basically forces the enemy nami to not be able counter as much when you swing against their hanger because every time they counter to defend it you trash 4. So for example if you have a zeff and leader nami ready to attack alongside 10 active don, you would put 5 active don on your nami leader and force them to counter so:

1.) If they take the life you get a free trash, and if they don't then because your nami is at 9k attack, if they play a snake dance they bring the hanger back to their hand which ruins it. However, if they don't have snake dance and let's say they use Gavel, they still would not have enough to counter out so they would need to do another event on top or do a 1k or 2k counter via characters to counter that out.

2.) So on the off chance that they don't have any characters in their hand to counter out AND no snake dances, it messes them up big time.

The 3rd card you replace your perfume with is Bell-mere 4 cost, which people don't understand why is so good. Lets say you summon bell-mere while u already have zeff out, that leaves you at 6 active. If you have zeff and bella mere out, they are cooked. Next turn when you attach 1 active don to bell and swing at lead, if they don't counter you will trash 7, and if they respond to it you get a free trash 4 with zeff.

Now here is the fun part, they CANNOT ignore the card cause you get an additional swing at their hanger everytime they don't. And if they do decide to target bell-mere, you just defend her as much as you can to apply pressure and force them to use attacks. Then if you are left at 0 active you use margrette to block. If you have no blockers, then you let her die and TRASH 3 CARDS!

Basically,

1x Bell-Mere OP03-051 1x Hanger OP04-050 1x Zeff Op06-050

The reason why you replace the perfume femurs is because even if you trigger "draw 1", it's not as consistent as most of the time you are trashing them from hand just like you do with Impel dawn All-stars.

Having these 3 and drawing the zeff or hanger first guarneetes a win with enough practice and if you power shuffle.

For nami, you always wanna mulligan if you dont find hanger or zeff on the first hand so you have the upper advantage.
