1: Nerf evo mega knight.
2: Nerf evo pekka
3: anyways, my suggestion is as follows.
Make evos interchangeable in game after accumulating an elixir threshold, hopefully ensuring a more strategic approach to playing an evo, eliminating the incentive to rapid-cycle your evo.
Personally, I would like to see a big update related to clan wars, also increase the rewards so that players are motivated to play this mode, and also balance the 14th and 15th level cards so that there is no advantage for one or the other player. Thank you very much! 
I think it would be cool to see daily challenges, like the event challenges but daily and zero losses allowed, you get rewards depending on how many wins you get
Can you add goldn steps for Champion league to up and evolution shards for free to players
2v2 Lader would be fire but i mostly want progression like maybe an new magic item to lvl up lvl 14 to 15 without requiring ewcs so its a little easier to lvl up
Maxbe add it to the lucky drops
Cosmetics for troops would be great, it could be an another source of income for the game. This is still better than making money out of overpored evolution offers . 
A new way to obtain more evo shards per season
heba pƶmpel
More evo shards a season and a rework of cw also plz bring the clan chest bqck
Trade tokens for Champions
More ways to earn elite wild cards and evolutions shards!!
collaborations!
3vs3.
incrase lucky drop like 3 per day same as brawl Stars.
I would love to see more wild shards in the shop. Maybe be able to buy 2 rather than just 1. I also think adding in some chests into the season shop could be a cool way to spend some of the season tokens.
Ladder system for 2v2 with own LB and everything
I would like to see a QOL improvement to the clan chat which allows you to react and reply to specific messages. This would make it much easier to communicate in active chats instead of having to refer to their message in your message.
I want to see some kind of game mode that gives good rewards like books, Evo shards etc.
I wanna see new special offers in clash royale. I mean i want to buy skins for towers. In the game we have so many good towers, but new players do not have the opportunity to buy old tower skins
I want to see 2v2 Ladder and Skeleton Journey added to Clash Royale, because the new features will make the game more diversified.
I think CR definetly should add pin trade in clans.
Why not have pin that you want by giving member pin you dont need?
I want 2x evo shards at shop
better mastery
rework clan wars
also evo log :0
Good Luck
Iād like to see a feature where you can join a tournament that you can participate everyday so you can enjoy more Clash Royale, like the old days , sponsored by supercellā¦ more rewards of courseā¦
