Suggestions for Pokemon TCG Pocket!

You are talking about different games with different cards and "sets"… and how does that make sense if they want to make money in Pocket?

People would just buy packs/codes from elsewhere (or get them for free through many ways) and wouldn't spend as much (or nothing at all) in-game purchases.

I agree, I also think it would be great if they added emoji reactions to battling. I understand that a chat is too much, especially because they're people who would use curse words and/or be mean, but whenever I battle someone and I see they have a really cool card I want to share my excitement about their card with them.

Less important to me, but what would also be cool is if you could send a little preprogrammed message after the battle, especially if you need to conceed because something came up and you can't finish the battle, like "Sorry, had to go" or even just "that was tough" or something for normal battles. Especially, because I've had battles that were really fun for me and/or really close and it just came to down to a coin flip who would win.

I think both of these things would make battling a bit more sociable and fun. I mean you don't just put your Charizard EX Hidden FullArt card in your deck for yourself, but also to show you have it and anytime my opponent brings out a cool card I feel like hyping them up for it.

I know you have an innocent perspective and it may be fun for the reasons you've mentioned, but let's not forget it can turn rude very quickly when in the hands of the wrong person. Not only could a wrong implementation make the game less fun for new players, existing collectors might feel resentment for competitive matches if done in a lackluster way. In one TCG I've played there became a culture of correct times to use an emote and it made interactions feel robotic and no longer spontaneous. I fear the worst for this innocent game.

yes, don't give them ideas on emotes… we TCG Live players know how annoying and toxic emotes are… not to mention the performance in mobile devices would be negatively affected by that feature.
