Best Card in Clash Royale

Listen up, simpleton. The game 'Clash Royale' uses cards to represent in-game items and characters. The joke here is a pun on the word 'card.' The punchline suggests that the best card isn't actually in the game; it's the real-world credit card that players use for microtransactions to buy advantages. It highlights the 'pay-to-win' aspect of many mobile games. You probably already know this, since you're always asking your mom for money to buy V-Bucks or whatever.
