If there is a monster on your opponent's side of the field and there are no monsters on your side of the field, you can Special Summon this card from your hand.
Rulings

You can only use the effect of "Cyber Dragon" to Special Summon itself during your Main Phase.

The effect of "Cyber Dragon" does not start a chain.
You can negate the Special Summon of "Cyber Dragon" with "Royal Oppression", "Solemn Judgment", or "Horn of Heaven".

Basically Cyber Dragon is one of the better part of cookie cutter decks right now in the Meta Game. If your field is clear and your oppoent has 1 or more Monsters and you have none you get a 2100 attacker at no cost. For people who go second in a duel this card becomes a demi-god on the field. The only probelm with Cyber Dragon is that to fully ultilize its effect your field has to be clear, also people expect to see Cyber Dragon with in a few turns of the beginning of the duel. So the summoning of your Cyber Dragon is expected which plays in your oppoents favor not yours. Overal Cyber Dragon is an mazing which should always be take in to consideration of adding or side decking for Regional Play and above.

Konami shouldn't have made Cyber Dragon and special summon...they should've either....

A). Kept its effect a Normal Summon like the anime did

B). Give it a Guardian Grarl or Swift Gaia the Fierce Knight effect (Normal or Special Summon, doesn't matter) where it has to be the only card in your hand.

At least then, it probably wouldn't be the big CC card seen today...

I pick choice A. I think that would have kept it super playable, but not super broken. I don't care for choice B. We already have cards that do that.

Yeah..I think having it as a Normal Summon would make it a lot more balanced.

Argeed. This is its most broken aspect. The attack power doesn't bother me at all. The speed it all that is important. I would run Gilasaurus if my opponent didn't get to Special Summon.

Yep...just like you could do so in a Skill Drain Deck, lol. Fun when the opponent goes "I'll special summon..." "Wait! Skill drain is out! You don't get a summon!" "What?!" XD
