Card Beasts: I Got the Myriad Worlds Gacha System from the Start

[Beast Taming + Cards + Gacha System + Power Fantasy + Female Lead] [Icefield Wolf - Moonhowl Wolf King - Ice Demon Werewolf - Frostnight Wolf Lord] [Thunder Spirit Dragon - Demon Thunder Dragon - Thunderflame Dragon Emperor - Silent Thunder Dragon God] [Goofy Penguin - Sword Penguin - Twin-Blade Penguin - Peerless Penguin Emperor] What should I do? They all seem so strong. Which one should I send out to let the other side lose with a little dignity? What? I drew another great one! Looks like I'm about to become invincible again. Lin Xiu had awakened an SSS-rank beast-taming talent. Looking at the unreliable System before him and the few card beasts with their bizarre personalities, he couldn't help questioning his life choices. (P.S. The author is a decent person. Please don't get the wrong idea!)
