>General principle
Look up TCG guides Youtube. I like this guy, he posts the deck code in every video description:

>Coins
Use the "search for players" button to find challenges in the overworld. They tend to be easier than real players and there's already a guide for them.
>Elemental Reactions
Play a deck with 3 different elements. Mona/Fischl/Collei is a classic.
>8+ Damage
Play a deck with Mona and UNMATCHED.
>Action cards
Fill your deck with 0 and 1 cost cards and spam them at every opportunity.
>Summons
Play Oceanid or Chiori.
>Burst
Use cards with low cost bursts.
>Shield
Put Zhongli, Noelle and/or Citlali on your team.
TLDR copy players that like the game, keep grinding and you'll get them eventually. Good luck anon.
