So I had some people ask me about the egg in the raid battles. So here's that card.
The egg is a pokemon that you battle and if you win you have the chances to capture that pokemon. You also revives special pokeballs for that pokemon long with 3000 xp points and items.
20 players can play at a time and it does not matter the team either. Which is good because some poke cp can be over 4000. So heads up.
To join a raid battle you need a pass for this kind of battle. Which you can buy in the shop or get it from a random gym. But if you get one from the gym you only get one play a day.
