So, a preamble - just be aware that trying to advance in Tag arena can get expensive very, very quickly, both in terms of silver and books.
Team1 (eventually): Note that this team REQUIRES all three non-Wukong members to have Lightning Cage and Stoneskin. All four also want to be AS SLOW AS POSSIBLE, which I know is counterproductive, but you want them to waste their moves on you while you are immune
- Sethallia - 500+ ACC
- Gaius - 350+ ACC, all other stats in ATK
- Shazar - 350+ ACC, 100% CR, all other stats in ATK
- Wukong - 500+ ACC
Team1 (until you can do above): Run this against their speed nuke team
- Mithrala - combined 700+ ACC/RES, 250+ SPD, rest into HP/DEF
- Pythion - despite being on your CB team, I expect he's probably still just fine to use here as-is
- UDK - slow as a rock, all stats into HP and nothing else. guardian or stoneskin set
- Harima - usual arena nuker stats
Team2: Run against their tanky team
- Arbiter - fast. 300+ SPD. other stats are irrelevant, but try not to make her *too* squishy
- Yumeko - fast. 250+ SPD. 500+ ACC
- Wukong - fast. 250+ SPD. 350+ ACC. He's mostly insurance, but helps for damage
- Foli - damage. he's your win-con. CR/CD.
Team3: Run against one of their teams without speed boosters
- Demytha - as fast as possible. 270+ SPD min. no other stats matter
- Archmage Hellmut - stats are irrelevant, just make sure he's faster than Seer
- Uugo - just here to deal with annoying champs like Leorius. faster than Seer, all stats go into ACC
- Seer - slower than the other three, but not too slow. Priority stats are CR and CDMG
