Losing to overlevelled playera

I returned to CR after 3 years and managed to reach executioners kitchen with hog eq cycle. Idr clash royale being this much pay 2 win i literally get paired up with players having level 13 and sometimes even level 15 cards at king tower level 11. Any tips so I can collect wild cards to upgrade my deck. I also used my book of common and rare cards to upgrade my firecracker and hog rider.
