Checking on a ruling that a guy said I was wrong on, but I doubt it.

Opponent has one monster on the field and 1 set face down monster. Ends turn.

I play shallow grave and he chains scapegoats thus filling up his field. Does Shallow Grave fizzle? I think it would, but not 100%.

Now I play Lightning Vortex clearing his field and set one monster and play book of taiyou on my newly placed Cyber Jar. He tries to say I can't due to him already playing scapegoats which would not allow him to summon that turn. I corrected him and said I could, but he can't summon so any monsters that would be summoned would have to be sent to the graveyard due to scapegoats effect.

Is this right? Also, going back to where I set Cyber Jar, if it were in my graveyard could I play Shallow Grave if he had used scapegoats? Meaning he can't special summon, but shallow grave says he can. What would have happened there? Not sure so I didn't do that. My guess is that since he can't special summon I couldn't activate it. Please help.

he doesn't have to get a monster if he can't. if he has no monsters in his grave then he wouldn't get anything in the first place so no it would definately activate for you.

as for the cyber jar part, i don't know what happens to his side of the field but you would still get the effect of cyber jar. you are under no such prohibitions for summoning. and i think the effect of cyber jar would override the scapegoats effect

***Opponent has one monster on the field and 1 set face down monster. Ends turn.

So in this situation he just eliminated his option to special summon by filling his field, but I still get to resolve my monster choice. Correct??

So you are saying that since his card prevents him from summoning that I cannot activate my card now due to him playing scapegoats or would it go back to the Cyber Jar scapegoats ruling where any monsters that would be summoned are instead destroyed? Not sure about these rulings.

As for shallow grave vs scapegoat. You are correct, you can special summon but your opponent cannot.

As for cyber jar vs scapegoat. You are correct, you special summon and your opponent sends all monsters that would've been special summoned to the graveyard..... from Ronin....

Now if scapegoat was activated in turn earlier you CANNOT activate shallow grave. You can't activate shallow grave unless both players can special summon a monster.

Actually, that rule means that both player's have to have a monster they can legally summon and it can't be used if they

1. Don't have a monster in their graveyard

2. Have monster's they cannot special summon.

So as long as that requirement is met, The Shallow Grave can be used. It's like how, even if the monster you select to remove with Book of Life is removed from the graveyard in a chain, Book of Life will STILL resolve as its activation requirement was already met.

Well hopes this clears this scenario once and for all....

errr well alot of the quotes you guys have posted, are contradicting to what you all have posted, maybe iv been playing vs system to much, but i think it should happen like this.

If you activate shallow grave (and both players can SS a monster) and then your opp. chains with scapegoat, shallow grave will still work for your, because shallow grave would only check for both players being able to SS when it was activated NOT when it resolves, hence you get a monster, your opponent dosnt.

now if they activated scapegoat prior to you playing shallow grave... your screwed and cant play shallow grave :).

as for cyber jar... err.... hmmm O.o im confused, when you all stated that your opponents monsters go to the graveyard instead of the field, because they played scapegoat, did you mean that your monsters also go to the graveyard, or just whoever activated scapegoat?

Only the player who activated scapegoats will have their monsters destroyed. The owner of Cyber Jar would still keep their monsters.

Think of it this way. Just because your opponent activates and properly resolves Scapegoats it does not impede you from Normal/Tribute/Flip/Special Summoning any monsters. The restriction applies only to your opponent. If you were to Flip Summon (or Book of Tayou) your face down Cyber Jar, Scapegoats will not negate the summoning, nor is there any effect currently on the field that would negate Cyber Jar's effect so Cyber Jar will resolve. All monsters will be destroyed (including the tokens) and both players will reveal the top 5 cards of their respective decks. Now when your opponent attempts to special summon his Level 4 or lower monsters he will be unable to do so because of the condition placed by him having activated Scapegoats earlier in the turn. The monsters that he would have special summoned this way are then sent to the graveyard.

As far as the Shallow Grave question, If Scapegoat is chained to the activation of The Shallow Grave, than the activation requirement of both players having a monster (one they can normally special summon from the graveyard) in the graveyard is met and you will attempt to resolve as much of the effect as possible. In this scenario only the turn player would be able to special summon a monster. If Scapegoats was activated earlier in the turn, or if your opponent has a full monster zone, you will be unable to activate The Shallow Grave.

Hope this helps.
