You are asking a REALLY BIG question.
It’s like a non-player asking “How do I play WoW?”
Nobody will be able to give you a simple, concise answer.
Here are just a few things to look for when making your team:
-
Coverage. Ideally, your team will have an answer for every family - a pet that is tough against that family’s attacks, or an attack that is strong against that family.
-
Heals/Shields - against multi-hits.
-
A Nuker - against a healer/shielder.
-
A Dodger - to avoid nukes.
-
A Weather-changer - so that if your opponent changes the weather in his favour, you can change it away from that, preferably in your favour.
-
Synergy. Pets that combine well so that one will boost the attack of another.
That’s the ideal. You ain’t gonna get it all, but those are some things to keep in mind.
I just had a look at your pets. You have more than enough to get going, though some of your breeds are sub-par. For example, an S/S Fiendish Imp is amazingly strong in PvP - and every other breed is garbage.
Then, every match has two equally important parts: 1. the team you make and 2. how well you play it. You always have to adapt to your opponent’s team.
The queue is not a conspiracy. But at any given time, except maybe at prime times near the start of Pet Week, there are few people in it, so they are inclined to adapt to the teams they see others using.
The best way to start to get a handle on teams is to look at the teams other people, especially experienced people, are playing.
Here is a page discussing the most commonly seen types of teams. Click the buttons for specific examples, with explanations of the basic plans in each case (WHICH YOU MAY NEED TO MODIFY DEPENDING ON YOUR OPPONENT!):
From that page, the general areas of Clonedance and AoE/Cleave are easiest for a beginner to grasp, since in each case, there is a pretty fixed plan for the battle, and your only concern is making sure your opponent doesn’t disrupt it.
Also check out three Youtube channels. All three of them are top players, and play very well in all areas, but in their videos, each stands out as instructive for me in a slightly different area:
-
Llennoca - of the three, he gives the clearest explanation of why he’s playing one move rather than another during the battles.
-
Discodoggy - he often rambles on about other subjects while playing, so you may have to watch or skip through a lot to get to the nuggets, but when he makes a team on the spot, he gives a great example of how to put a team together. He’s all about coverage. He has a guide to the general principles of creating a team here: http://pvppetbattles.com/guides/creating-a-team/
-
Rosqo - does some great exposition on putting a team together to counter a current meta and what the plan will be.
Try some of all three, and see what speaks to you.
