Best free "CCG" games

GAME GENRE – Trading card games, often called collectible card games (CCGs), are games built around collecting cards and using them to create decks for turn-based battles. Each card usually has its own abilities, strengths, weaknesses, or special effects, and players must combine them carefully to build a deck that works well together. Winning matches can unlock new cards, while cards are often divided into different types, sets, and rarity levels. Part of the appeal comes from constantly improving a collection and experimenting with new combinations. Many modern CCGs are free to play but also allow players to spend real money on in-game currency, booster packs, cosmetic items, or individual cards.
