Yu-Gi-Oh Rulings 101?

I've decided to do this after thinking about it for a while.

Here's what I'm going to do, I'm going to give 10 situations and the rulings for each one

Then, you guys can answer this question by giving me a respond, or ask a ruling question

I'm thinking about doing this every once a while when I gathered 10 good rulings to announce, some will be quick, and some will be slow, but in the end, you will have an answer.

1. Pot of Duality vs Future Fusion

Q: Can you activate Pot of Duality the same turn you activate Future Fusion?

A: Yes, however, you cannot activate PoD the turn that the fusion monster is summoned via Future Fusion

-Ruling

1) If the 'Activation' is negated, you're allowed to special summon or activate another Pot of Duality

2) If the 'Effect' is negated, then you're not allowed to special summon nor activate another PoD

2. Exodia

I have made this mistake before, but I've learned my lesson

Exodia is an effect monster without an effect, the part to win the duel is a 'Win Condition', it's not continuous, so this is why Exodia cannot be negated by anything.

3. Optional Triggers

Optional Trigger effects are commonly missing the timing, however, people intend to misunderstood them

a) "If x happens, then you can ...."

b) "When x happens, then you can ...."

In example (a), that's a 'If, you can' optional trigger which will not miss the timing, it only cares if the requirement(s) is/are met.

In example (b), it's a 'When, you can' optional trigger that will miss the timing if the last thing that happened was not meeting the requirement(s)

4. Psi-Blocker

In order to understand Psi-Blocker fully, you must understand the rulings for 'Prohibition' first. Sure, Psi-Blocker and Prohibition is different, I agree, however, most of the scenarios that you will come across can be found in the rulings of Prohibition.

If Psi-Blocker is on the field while Royal Decree is active, and you declare Royal Decree for Psi-Blocker's effect, Royal Decree's effect will no longer apply until the effect expires. And no, removing him from the field will not stop the 'Lingering Effect'

-Ruling

1) The card you declared can be used as cost

2) The card you declared cannot be used as a synchro material monster

5. Necrovalley

As some of you know, Necrovalley recently received an erratum, which threw many people off. But really, nothing major has changed, here are some 'new' stuff that has been ruled

1) This card no longer negates, it lets the card 'Resolve without an effect'

2) 'Affect' generally means physically moving the card out of the grave to elsewhere

3) Cost that 'Affects' the grave will not be stopped by Necrovalley

4) Cards such as Plaguespreader Zombie or Stardust Dragon has no conflict with Necrovalley

6. Quick Effect vs Damage Step

Q: Can a Quick Effect be activated during the damage step?

A: If the Quick Effect is able to negate Activations, then yes, otherwise, no it cannot

-Skull Meister is an exception in which it does not negate activation but is allowed to be activated during the damage step

7. Light and Darkness Dragon

Q: What happens if LaDD does not have 500 atk / def to lose?

A: Many will say that LaDD cannot negate any longer, and that is correct, however, if I was to go into more detail, due to LaDD being mandatory, it will still be chain link 2, then when it's LaDD's turn to resolve, it will resolve without an effect.

Example:

Chain Link 1: Jar of Greed

Chain Link 2: LaDD (800/400, but it still activates)

Chain Link 3: Chain Strike <-- this is why LaDD being Chain Link 2 may be important

8. Solemn Judgment

Q: Can Solemn Judgment negate a normal summoned via Ultimate Offering?

A: No, in TCG, it is ruled as the normal summon is caused by an effect, therefore, Solemn will not be able to negate that normal summon

9. Karakuri

The new archetype 'Karakuri' has been throwing people off.

-Rulings

1) If a Karakuri is in def mode, you do not have to attack with that card

2) If a Karakuri is in atk mode, you are required to enter your battle phase and cannot leave until you've attacked with a Karakuri monster

3) If you're prevented from attacking (Gravity Bind, Level Limit, etc.) while you control an atk position Karakuri, you are required to enter your battle phase as well, then proceed to end phase from there

4) If you skipped your battle phase by a card effect (meaning you cannot enter your battle phase), you do not have to attack with a Karakuri monster

10. Phantom of Chaos

Q: What happens if Phantom of Chaos has already changed its name, but later on Skill Drain/Forbidden Chalice negated the effect?

A: It will keep the monster's name, atk, def, and effect (of course negated though) of the monster until the effect wares off, however, no
