Im going for Kushina, its cheaper and you can get masked man in other events whereas we have only seen Kushina twice so far.

100% not biased, masked man, not cause i run a full uchiha lineup control cancer team, not cause i like obito and def NOT because i have a sharingan, but masked man

personally i would go for masked man, but kushina is not bad choice either besides she's really cheap, tho it's entirely up to you and what you prefer.

I would also go for masked since he not only removes immunity but also removes buffs/ shields and immobilizes with chase and that mystery. He is squishier but has a dodge.

egh *..still can't decide :/

Power then....

Key probably good since rebate is this week .

but for your Question , i would say masked man .

if you own jonin minato then kushina habanero is indeed a better option since synergies very good with him and breeze dancer.

masked man, The ONLY real counter to cancer teams like 1010 mabui and light main blitz where every ninja except the main is * and their goal is to buff main and kill 1 of your ninjas whihc is 99% of the time your slot 1. Masked m*so has the ability to lock out double healer teams if you use him with itachi anbu or fire main. So bottom line masked main is the way to go if you don't like cancer round 1 desperate blitz teams. Oh and masked man c*so counter those edo deidara teams that buff him and call it a day by shutting down deidara before or during his mystery as deidara is the only one that does like 70% of that teams damage you basically win the fight if deidara doesn't pull his mystery off.
