Summoning 105 water elementals with Tazar and a mass prayer is a very good support for Goshi's implosion. The implosion doesn't remove the stack of summoned water elementals, and against Tazar's defense, plus the mass prayer, only archers deal significant damage. I watched half the round – I think Tazar will at least not lose.

P.S.: After finishing the second half of the battle, I can already say that Tazar is the favorite here: 48 water elementals remain after the implosion, and then he summons more – do the math...
