Chaos Sorcerer... this card reminds me of the good old days before Synchros and Xyzs. A relatively old card, this sorcerer is still plenty alive in the metagame. Historically, it has typically been overlooked in favor of its overall 'better' brothers, the now banned Chaos Emperor Dragon - Envoy of the End, and Black Luster Soldier - Envoy of the Beginning, who as of now has been enjoying his new Limited status. Anyways, Chaos Sorcerer is a decent enough card to have in a deck. It's a 2300 ATK-Special Summon Beatstick with a relatively easy summoning condition and above average effect, not to mention it is currently unlimited, letting you have three copies of this awesome card in your deck.
This card was primarily played as a 'substitute' of sorts to replace the much more awesome Envoys, but their recent status has given Chaos Sorcerer his chance at the limelight. Chaos Sorcerer's strength in this metagame comes from the fact that you can just drop him down in the middle of the Duel and banish that guy's Stardust Dragon/Judgment Dragon/Trump Card that is very difficult to get rid of. His chances of getting in your hand are three times greater than BLS's is, due to its position on the banlist, so I think it is more reliable.
Strategies and game play:
This card's effect is pretty straightforward, drop it down in the middle or endgame, and dish out its awesome 2300 power, or use its almighty power to banish that pesky monster your opponent's gotten a hold of. Just drop da bomb and this card could possibly turn the tables in your favor. Of course, Black Luster Soldier - Envoy of the Beginning is still generally better, so this card is mainly used as a stand-in until you get the big guy.
Combos with other cards:
Chaos Sorcerer + Soul Absorption: Gain 1000 Life Points when you Summon this card, and another 500 each time you use its effect.
Chaos Sorcerer + Soul Absorption + D.D. Survivor/ D.D. Scout Plane: Use Chaos Sorcerer's effect to banish either of the D.D. Monsters to gain a 500 Life Point boost while getting the monster back in the End PHase.
Chaos Sorcerer + Burden of the MIghty: Hardly anything can stand up to this card's 2300 ATK with the Burden of the Mighty in place. It helps Chaos Sorcerer stay alive longer.
Chaos Sorcerer + Skill Drain: A quite risky but effective combo. Activate its effect to banish a monster, then activate Skill Drain so it can still attack. Of course, subsequent uses of its effect will be impossible, but it is relatively unaffected compared to other cards which are decimated by Skill Drain.
Chaos Sorcerer + Helios - the Primordial Sun/Helios Duo Megistes/Helios Trice Megistes: The cards gain an attack boost each time Chaos Sorcerer avails of its effect.
Ways to counteract it:
Several cards can prevent this card's Summon like Imperial Iron Wall or Koa'ki Meiru Drago. Additionally, D.D. Crow and Soul Release can banish the monsters necessary for this card's Special Summon before you can banish them.
This card's Summon can be negated by Solemn Judgment, Solemn Warning, or Thunder King Rai-oh.
This card's effect can be negated by Skill Drain, Destiny HERO - Plasma, Koa'ki Meiru Doom, Shadow-Imprisoning Mirror, Divine Wrath, or Doomcaliber Knight.
This card can be destroyed through normal means like Lightning Vortex, Bottomless Trap Hole, Mirror Force, Dark Armed Dragon, etc.
This card can be removed from play normally via Dimensional Prison, Dark Core, Black Luster Soldier - Envoy of the Beginning, another Chaos Sorcerer, etc.
This card can easily be beaten by a large number of card due to its measly 2300 ATK, and because its effect doesn't activate on an opponent's turn.
This card is an easy-to-Summon-ready-at-just-about-any-time-2300ATK-beatstick with a not too bad effect.
You can have up to three in your Deck.
Not many effects negate banishing; mostly they negate destruction.
Has a 'weak' ATK compared to other 'boss' cards in today's metagame.
Can be negated/destroyed in many different ways.
Is overshadowed by Black Luster Soldier - Envoy of the Beginning.
Artwork and aesthetics:
I think, personally that the picture is just badass. Here we have the Chaos Sorcerer looking as scary as his description should make him look. As for meaning, well he is shown holding white and black energy orbs, probably representing his Summoning conditions. Overall, 10/10 art rating.
This card is incredible, but as I've stated many times, it is easily countered by many cards and overshadowed by the Envoys.
