My observations and thoughts about the Tournament. This week I had the Sully/Cho/Dr. Ion comp, which wasn't too stressful. Since you'll be facing the children of the Celestials every week, however, it's a good idea to get well-acquainted with them.
--------Xu-Fu, Cub of Xuen-------- Beast
Feed - 4 turn CD, 90% hit chance. Deals beast damage and heals the user for 100% of damage dealt.
Spirit Claws - 80% hit chance. Deals beast damage. Always hits during Moonlight.
Moonfire - 3 turn CD. 100% hit chance. Deals magic damage. Turns the weather into Moonlight.
Xu-Fu's attack pattern is simple: initiate with Moonfire, then use Spirit Claws each round until he's at 75% health or lower. Once Xu-Fu is down past 75% health, he'll use Feed on cooldown. If Moonlight expires or the weather is altered, he will use Moonfire once it is off cooldown.
Feed is the biggest problem of this fight, without which Xu-Fu is similar to Lil' Oondasta or Kafi (that is, a straight up brawl to see which team expires first). It's recommended to lead off with a pet which can deal extra damage to Xu-Fu via Mechanical attacks and tank his hard-hitting abilities, but the most important consideration of the fight is to neutralize Feed. This means that Mechanical pets with a damage reduction or dodge, or a Flying-type pet with a damage neutralizer, are ideal for this fight.
- Darkmoon Zeppelin (1, 2, 2) - Decoy can be used to evade Feed when you know that it's coming on the next turn, and on the final turn Explode takes out a chunk of his health.
- Any moth (x, Cocoon Strike, x) - Moths hit hard and all have the Cocoon Strike ability which fully soaks a single attack.
- Any pet with Call Darkness; Crows work especially well.
-------Zao, Calfling of Niuzao------- Beast
Trample - 100% hit chance. Deals beast damage + 10% of the targets health.
Niuzao's Charge - 4 turn CD. Wind-up attack where he charges up for one round and then deals 1000+ Beast damage the next.
Wish - 5 turn CD. Heals target for 50% of health on the next turn.
Similar to Xu-Fu, Zao has the nasty combination of hard-hitting attacks coupled to a powerful self-heal. His attack pattern consists of using Niuzao's Charge on the first two rounds, then Trample on the next two, and then Wish on the fifth. Trample on the sixth turn, Wish goes off. Repeat.
You have two viable ways of dealing with this guy: overpower him, or neutralize the healing and whittle him down. If you choose to overpower him, you have six turns to wipe him out before Wish undoes much of your progress. This means the Legendary nuke combo is viable since Zao has no avoidance moves - alternate methods include Call Lightning with Black Claw + Hunting Party. If you choose to go the attrition route, you will almost certainly need a pet that can dodge Niuzao's charge (Dive, Submerage, Cocoon Strike, Dodge, etc.) and a move to reduce healing taken (Call Darkness). Using this strategy it's viable to have two such pets and use a hard-hitting single target pet as an anchor, such as Lil' Tarecgosa or the Darkmoon Tonk.
-------Chi-Chi, Hatchling of Chi-Ji------- Flying
Fire Quills - 100% hit chance. Elemental damage. 1-2 hits, hits an additional time if the user goes first.
Ethereal - 3 turn CD. Always goes first. Chi-Chi avoids all attacks for the round used.
Tranquility - 2 turn CD. Heals ~300 HP or more per turn. Lasts 3 rounds.
Chi-Chi is a test of endurance against a foe who brings a gun to a knife fight. She always opens with Tranquility, then Ethereal, then Quills, then proceeds to use Ethereal on cooldown. More testing is needed to determine exact conditions for her use of Tranquility, as I only saw it used once in my battles with her.
With a dodge move, a powerful self-heal, and an attack that does respectable amounts of damage, Chi-Chi may not take your pets down as quickly as Xu-Fu or Zao but gets correspondingly higher defenses in turn. Fortunately, much like the Pandaren spirit tamers, Chi-Chi has an Achilles' heel: Snails. All snails have Ooze Touch, a magic attack which deals extra damage to Flying creatures and which can be coupled with Acidic Goo to act as a constant DoT and a damage booster. Dive is a good move to use on the turns when Chi-Chi turns Ethereal, as it helps avoid the next attack and occupy an otherwise wasted turn. Your ideal battle team setup is therefore three snails all running Ooze Touch, Acidic Goo, and Dive.
- Snails: see above.
- Sprite Darter Hatchling or Nether Faerie Dragon: Increased damage against Flying and Life Exchange make them powerful lead pets.
-------Yu-la, Broodling of Yu-lon------- Dragonkin
Jade Breath - 100% hit chance. Deals Dragonkin damage.
Emerald Presence - 5 turn duration. Reduces incoming attacks by around 150.
Lift-Off - 4 turn CD. 1 turn duration. Lift off and becomes unattackable for one round, then dives on the opponent for Flying damage.
Yu-la is the odd pet out as she does not have a heal but rather comes with damage reduction. Her attack pattern consists of putting up Emerald Presence, then Lift-Off, and then using Jade Breath until Emerald Presence expires, upon which the pattern repeats.
Being a Dragonkin, Yu-la is naturally weak to Humanoid types, most of which can make significant dents in her (although keep in mind that the common Crush attack has only an 80% hit chance, meaning that sooner or later you WILL have RNG losses if you use a Humanoid setup). Multi-hit attacks should be avoided, and pets which can evade or neutralize her Lift-Off attack will have a big advantage in the battle. As Yu-la doesn't heal, winning the battle is mostly a question of staying ahead of the damage that she'll be dishing out to you. You can also take advantage of the lack of damage in the first two rounds to bring in wounded pets, use a healing ability, and then quickly flee, as fleeing an elite pet battle does not incur a health penalty.
- Anubisath Idol (1, x, 1) deals high damage with Crush and can use Deflection on the Dive-Bomb move to negate damage entirely.
- Kun-Lai Runt (2, 2, 2) is faster than Yu-la once Yu-la is chilled. Takedown does increased damage, and double damage against frozen targets.
- Hopling (1, x, 1) is faster than Yu-la innately and can gain an extra turn by using Backflip.
To Do List
- Figure out if there is a way to quickly power-level pets by fighting a tamer team with two pets, carrying a third, dropping the scenario and then requeue-ing into it immediately again. The four boss-level elites only give about 195-ish XP to a level 24 pet - what about the tamers?
