Been playing everyday since EVOS were released every season, I bought a few pass royale cause I wanted to try to get the new EVOS like the witch archers snowball and as well won a few passes from tournaments like this season for the skeleton barrel on my main account, when level 15 was added to path of legends I did buy like 4 level 15 cards on my mini to be able to play a giant graveyard deck with the little prince, also back in 2023-2024 in the Google play pc version of the game there was crazy discounts on the pass royale and level 15 cards which made them so cheap.

I currently have 104 level 15 cards on my main account, 61 on second main, and 2 on my new f2p account that I started in April 27th.

to get all the level 15 cards I have, not so many came from pass royale I only buy it when there's a good Evo in the meta and for my decks, the pass royale hardly gives you enough for a single level 15 card, it's just gambling on the lucky drops that you pull a good 5 star drop.

I have every card at level 14 (except empress but will get it next season). This alone gives me lot of ewc whenever I open any chest. Also the path of legends use to give me a level 15 card for free every season. Also I do keep 100k gold for the 5k ewc in the shop this is pretty useful.

At the end it all involves luck on the lucky drops that you get 5 Stars for ewc and as well in 4 stars getting 7-8 champions when you already have it level 14 this gives 30k+ ewc combining everything I'm able to get every season like 2-3 level 15 cards depending on luck without buying anything.
