The one of the goals of the TCGO seems to be to emulate the experience of playing the card game in real life, and the single player campaign takes you through a tournament hosted by a fictional game store, with 15 AI opponents (all with unique personalities and flavor text, including some good-natured trash talking), who you challenge through four leagues of 12 games each for a total of 48 games
The effects of monsters allow you to flood the field with monsters, giving you the materials to Xyz Summon Number 5: Doom Chimera Dragon

Encroaching Dragonstorm, Breaching Dragonstorm, and Corroding Dragonstorm all can be effective when played multiple times
