The 'Envoy' cards are current banned. Chaos decks, which use the Envoys, can only really be beaten by other Chaos Decks, or something that can easily pull off an FTK(First Turn Kill)
Build a better deck.
Chaos Sorcerer has no practical advantages over the Envoy of the Beginning. The card's value was that it was easily summoned and had a great effect, not as strong as the Envoy but strong enough to be worth including in deck.
Add Mask of Restrict to your deck. (it keeps anyone from tributing, you included)
A chaos deck is a deck that runs mainly light and darkness monsters where the light monsters are not lightsworn monsters. The focus of this deck is summon the chaos monsters(Black Luster Soldier-Envoy of the Beginning, Chaos Emperor Dragon-Envoy of the End, Chaos Sorcerer, and Dark magician of Chaos) while preparing to summon the chaos monsters this type of deck is also removing from play the opponent's monsters from play. This deck gets its name from not only from the monsters but also the booster pack in which this card were first released; Invasion of chaos. This deck works wonder with Dark Armed Dragon.
with an other crystal beast deck!
Impossible, unless your deck can already beat them.
i dont know who he is
With skill, depends on the deck your opponent uses.
If you have a deck that needs monsters sent to the graveyard like a lightsworn deck, then you might win.
beat the game then it will tell you what to do after.
The best deck is what you like and how you use it, there is no best deck just like water puts out fire and so on there is always a meta-deck that will always beat another meta-deck.
O heck yeah I got 2 deck that going to beat any duelist.
