The Rules Differences page has been updated, as Spirit Monsters were discovered to have a functional errata / ruling related to their mandatory End Phase Trigger Effects. Apply the following ruling for Spirit Monsters, Lightsworns, and any mandatory Trigger Effect that activates in a certain Phase:

• This effect keeps activating (if its activation is negated) until it finally resolves (even if it resolves negated) [REF].
  

Also, the Functional Errata page has been updated to include "Mark of the Rose", as it has recently been pointed out to have 2 Trigger-like Effects up until its erratum in Fusion Enforcers [REF]. The individual card rulings have also been updated.

• These Trigger Effects won't activate while the effect of "Cold Wave" lingers.
  

After many months of investigation we've reached a roadblock... there's no evidence that Konami's rulings change [1] regarding "Rivalry of Warlords" and "Gozen Match" took effect at or before SJC Edison. Thus the responsible and prudent course of action is to apply the Upper Deck Entertainment rulings [2] to the cards. This change only affects the ability to Tribute Summon (not Special Summon).

 Moving forward, apply these UDE rulings to Rivalry and Gozen: 

• If you have only 1 monster on the field face-up, you may Tribute it for a monster that is a different Type/Attribute.
  
• If you have 2 monsters on the field face-up of the same Type/Attribute, you cannot Tribute 1 of them for another monster that is a different Type/Attribute (even "Jinzo") as you would then have 2 different Types/Attributes.

Discord user Shining Blue-Eyes has unearthed mounds of evidence concerning the validity of a 2004 Netrep ruling for "Ultimate Offering":

• "The Summon produced through the effect of "Ultimate Offering" may be negated only if that Summon was the first link of a Chain." [REF]

The Netrep ruling fell out of use and judges were of the opinion that the Effects themselves performed the Summon, that it was not a manual player action.

TL;DR: in Edison Format, a Summon performed by "Ultimate Offering" / "Mausoleum of the Emperor":

• cannot be negated by "Solemn Judgment"!
• can be responded to by "Torrential Tribtue" if "Ultimate Offering" was Chain Link 1.

Likewise, "Solemn Judgment" cannot negate the Synchro Summon performed by "Urgent Tuning" (even if it was Chain Link 1).

In an email sent out to Official Tournament Stores (OTS), Konami announced several new alternative, yet officially sanctioned tournament types. 

The "Time Wizard" format allows stores to sanction legacy formats such as: Edison, Goat, HAT, ETC.
