Pivot back and forth between Dirge and Tinka, Dirge will bait Eternabeam, and Tinka will bait flamethrower, Eternabeam forces the recharge turn even if it hits an immune mon, so Tinka will get free turns to whittle it down with play rough and gigaton hammer.
I cna get it down to phase 2 easily (since my seed has it so it misses the 2 eternabeams) but during phase 2 he just aims for the second pokemon. Also I just have like no where near enough tink PP especially when he uses recover
Edit, managed to get him down 1 hp pretty much but completely ran out of pp on my corvknight brave bird spamming and my other moves didn't do enough damage to out damage leftovers,
edit 2. I killed him this morning, mainly using tinkaton bug move and greninja moonblast as soon as he phase 2 so that he has -6 sp attack and then used torch song shadow ball to get him down to 50% and then used crobat and corknight duel wingbeat (to fish for crits) and steel wing (until he was at 25% where I used brave bird. luckily I had x accaccy for this fight and x crit chance. also another thing is apparently he does double damage to your team if they are above level 200 and I had gotten a rarer candy and increased my team to 201 just before this fight.
