Goat Format · April 2005
What the Goat Format rulings add to, or change from, the rulings above.
You may flip Ultimate Offering face-up during any phase of play and during either player's turn. This much is fine. You can only activate its effect of additional normal summons during YOUR Main Phase 1 and 2, and during your OPPONENT'S Battle Phase. This means you could flip it face-up during your opponent's Main Phase 1 and then activate its effect during their Battle Phase.
The Summon produced through the effect of "Ultimate Offering" may be negated only if that Summon was the first link of a Chain.
A player may not Tribute a monster to be Summoned by "Ultimate Offering" until that monster is Normal Summoned/Set to the field.
Q: If I declare an attack and my opponent uses the effect of "Ultimate Offering" to tribute the monster I am attacking for a higher level monster, does my attack continue? A: A replay would occur because the target of your attack is no longer on the field. Play will return to the Battle Step. You are not forced to attack the new monster. Curtis Schultz, 12/08/2003
Q: If a player has an active "Ultimate Offering" on the field, can their opponent use the effect? A: Only the controller of "Ultimate Offering" can use its effect. Curtis Schultz, 02/13/2004
Q: Can "Ultimate Offering" chain to itself? A: Yes, it can. bishop 02/23/2004
Q: Can you use the Spell or Trap cards brought to the field through the effect of "Magical Hats" as a Tribute using Ultimate Offering? A: Yes, you can offer the face-down non-monster cards selected from the effect of "Magicial Hats" as Tributes for a Tribute Summon using "Ultimate Offering." The non-monster cards are being treated as monsters during that Battle Phase, so it will okay to do this. You would need to resolve "Magical Hats" first in order to get the non-monster cards into play, then activate the effect of "Ultimate Offering" afterwards. Curtis Schultz, 02/02/2004
Q: If an Effect Monster such as "Sonic Bird" is summoned by the effect of "Ultimate Offering" during the opponent's Battle Phase, will the effect of the monster still activate? A: The Summon performed by "Ultimate Offering" during the opponent's Battle Phase is still considered a Normal Summon… So if you choose to use its effect and Summon a "Sonic Bird," the "Sonic Bird's" effect will after it is successfully Summoned. Obviously this will not happen if you were to Set the "Sonic Bird." Curtis Schultz, 01/25/2004
Edison Format · March 2010
What the Edison Format rulings add to, or change from, the rulings above.
The summon does not happen "immediately after this effect resolves". It can't be negated by "Solemn Judgment".
You can chain this effect to itself, even if you only have 1 monster in hand.
If "Ultimate Offering" is face-up, you can activate its effect multiple times in the same chain.
When you activate the effect of "Ultimate Offering", you pay the 500 Life Points as a cost at activation, and then the Summon occurs at resolution of the effect of "Ultimate Offering" in that chain. This means that it is possible to Summon a monster in the middle of a chain with the effect of "Ultimate Offering".
If you are using the effect of "Ultimate Offering" to perform a Tribute Summon, you Tribute the monster when the effect of "Ultimate Offering" RESOLVES and you perform the Tribute Summon, NOT when you activate the effect of "Ultimate Offering" and pay the 500 Life Points.
If your opponent activates a Trap Card, you can chain the effect of your face-up "Ultimate Offering" to the Trap Card to Tribute Summon "Jinzo" (if you had a monster on the field to Tribute) and negate the Trap Card's effect.
If you activate the effect of "Ultimate Offering" to Summon, and your opponent chains "Mystical Space Typhoon" to destroy "Ultimate Offering", the Summon does not resolve because "Ultimate Offering" is a Continuous Trap Card and is no longer on the field.
You can activate the effect of a face-up "Ultimate Offering" during your Main Phase even if you have not done a Normal Summon yet this turn.
