The acronym for the English game would be TCG~
A Light Beatdown and you're not running Cyber Dragon~? Or Mirage Dragon to stop those armours? Hmm... I can't rate or fix this much because of a few reasons, number 3 being the most important:
1. I'm very sketchy on the TCG.
2. I suck with Ritual decks lolz~
3. There's too many deck types for Light creatures. From the top of my head, there's a standard beatdown, a Jackal lock, Silent Magic, Silent warrior, Shinato Ritual, Royal knight, Alaphabet, Cyber beat, Creator summon, Cybernetic rush, Magical Chaos, Angel drain, Angel Zeraato, basic Angel, Sphinx, etc etc
The list could probably go on lolz~
Since you like Light monsters, you'd appreciate the true GENIUS of my Cyber OTK deck, it's pretty much all light creatures. (I think there's 3 out of the 15 that arn't)
That'd make 5, making the deck illigal lolz~x3 Bottomless Trap Hole (two more are side-decked in, depending on who I am dueling)
