This is the best version of a Pure Charmer deck I can make at my current collection of cards etc. (I play paper)
A lot of the decks I see go too "all in" with the main deck and spread themselves too thin hitting every attribute at once. [I understand this since a lot of people use this site for Master Duel so no matches really] Most decks (yes some do) but most are only a few attributes and even multi attribute decks there are usually specific monsters in those that are problematic. So, that's what the side deck is for. The first duel will be a wash if your not typed up right but if you change out you might stand a chance. Let's be honest, this deck as a pure form is bad and if you play it you're not playing to win every game. Either way, if you do type it right you can disrupt your opponent by actually stealing monsters with your Charmers and further stealing with the link versions.
I'm not sure if there's much else to talk about... the three extra Extra Deck monsters are just one's I had in my collection to fill the 15. Feel free to slim down or expand as you see fit. Nothing in here is set in stone per se but I definitely encourage you making it in a specific set of Attributes first. The most trouble I have when playing in my own casual eviroment is Earth, Dark, Light, and Wind so those are the main deck ones I chose. (Well, I picked wind more because they have the best Spiritual Art in my opinon Water is a close second) Also, yes, I'm on a very tight budget for Yu-Gi-Oh so most of the cards you see here are from the Structure deck or other easily accessed sources from one point in time. I did not go out of my way to buy anything for this deck except the link monsters because for some reason none of those were included in the structure deck???
Final notes, Unpossessed is KEY to this deck's survival. I only own 2 copies so I don't know if three is better or if it clogs you up. Your charmers being able to survive battle and steal will make your opponent waste monster/card destruction effects on your face down monsters even when you bait them with an attribute that can't steal (well, depends on the opponent) but if you have Awakening of the Possesed they have to hit that first etc etc...
If you're a fellow Charmers Enjoyer, Good Luck!
