not worth it at all.

tsunade sannin war full skillbroken outclasses her in 1vs1 and tsunade sannin era outclasses her in 2vs2 and 3vs3.

Anyways, her fragments so far costed 250-300 coupons each one.

none uses her in 1vs1 simply because immortal teams don't stand a chance right now, regardless what version of tsunade you use, because too often you meet people with overstacked move 1 that wholly forgot what move 2,3,4 are + multiple ignition per round.

but the point is that wherever sannin war dies, also hokage and sannin era die, so... does it really matter?

(what's the point of looking at which tsunade you are using when you face agk or edo hiruzen blitz teams with overstacked move 1? Tsunade dies regardless in round 1 or at most in round 2 since she won't ever be your move 1. And what's the point of thinking about what tsunade is better to use when you face edo deidara + jinpachi or shisui + itachi anbu + fire main? You are so much ignited constantly that you never heal back 1 single hp).

So there's no point in looking at those cases.

The cases you have to look at are those where both the 3 tsunades survive after round 2.

Take the following team:

x x x

x Water Main Kushina habanero

Tsunade sannin war sakura cloak x

talents: 32332 or 32333, summon: eight bird, summon mystery: giant katsuyu level 3.

would you really put in the place of tsunade sannin war 5 stars full skillbroken one hokage tsunade or one tsunade sannin era 3 stars?
