Madolche + Small World

[sgamerman]

lots of ruling dispute at locals today.
1) Does Madolche Dessert have to return both targets to summon from the extra deck? (Ex: I activate Dessert to target Anjelly and opponents Fenrir, I chain Droplet to send my target as cost… can I summon from extra deck?)
2) If my opponent has rivalry of the warlords when I activate Madolche Dessert… I return Magiliene to hand (spellcaster), can I summon a fairy from the extra deck?
3) Chateau is on the field and im resolving Glassouffles shuffle 2 from grave effect. Some random guy was telling me I couldnt add one of the monster to the hand and shuffle the other. I had to either add both or shuffle both (thats not how it works in master duel)
4) Once I am resolving Small World, can I look my deck before revealing the card in hand? Just that same annoying random guy sitting next to me, this doesn’t actually matter too much unless you play against someone who is being annoying about rulings but I guess it’s cool to know. My opponent didn’t seem to care at all since revealing isn’t a cost, just the annoying guy. I guess you reveal first then choose a monster then add but is looking at your deck before revealing considering cheating? You’re still resolving a search effect

1. Unless it explicitly says to return "both" or "all" targets, it just needs to return at least 1.
2. Yes, because the special summon part of Dessert is optional, so Rivalry can't prevent you from at least resolving the return-to-hand part of it. Then, once you returned it to the hand, you no longer control a Spellcaster, meaning you can then summon a different type, thus still obeying Rivalry's 1-type restriction.
3. Madolche Chateau has the effect "If a monster(s) in your GY would be returned to the Deck by the effect of a "Madolche" monster, you can add it to your hand instead." Because it says "monster(s)" with the "(s)" at the end, it'll include every appropriate card that would be returned at the same time. So yes, in this case where you're targeting 2 monsters with Teacher's effect, you'd have to either add both to the hand or shuffle both to the deck. Master Duel has gotten certain rulings wrong in the past and mistakenly allowed certain cards to work in ways they shouldn't be allowed to, so I'd trust a judge ruling on this instead of whatever happened in Master Duel.
4. The way this would be ruled at your locals, and the way this would be ruled on Duelingbook, would vary. Normally, you're supposed to know ahead of time what cards you'd be able to search with your own effects before you activate them, but Duelingbook is lenient when it comes to that because Duelingbook features a "Check Options" button for Small World where you can select a card in your hand you'd like to banish for Small World's effect, then the game lets you know what you could banish from the deck with that selected card, as well as what you could then add to your hand. This special button, however, doesn't exist in the physical card game, so you arbitrarily looking through your deck, before you're actually authorized to, will usually be seen as cheating.

If I'm not mistaken, low-tier events such as locals do permit note-taking, while higher-tier events ban note-taking unless it's specifically to keep track of life points, mandatory effects, turns, or stat changes. https://img.yugioh-card.com/en/downloads/penalty_guide/YGOTCG_Policy_v_2_2.pdf#page=36

If your locals permits note-taking for Small World, you may make a note of which pairs of cards Small World could banish from your hand and deck, and refer to those notes every time you wish to use Small World as long as you don't take too much time doing so.

Thanks, that’s basically what I thought on all of them too. The only one I still question is the Chateau because it lets you shuffle just 1 on EDOPro too and I tried to understand why. I think it should be able to because Chateau affects the monsters themselves, not an effect. It says “if a monster would be returned to the deck by the effect of a Madolche monster, you can add it instead”, not “if a Madolche monster effect would return a card to the deck, you can add it back instead”. When Glassouffle us resolving, you are still only deciding once, except you are deciding on each monster individually…. Like “would you like to return Anjelly? Would you like to return Hootcake?” If one answer is yes, and the other no… one will be added while the other would just be shuffled like normal… there isn’t anything stopping the gamestate from returning one and adding one at the same time. Chateau doesn’t start a chain, it’s just a lingering effect that lets you add a monster that would be shuffled.

Regarding the Madolche Chateau card, you've raised an interesting point about how it interacts with the shuffling of monsters back into the deck. Can you explain in more detail your understanding of how the Chateau's geometry dash breeze effect works, and why you believe it should allow you to selectively add monsters to your hand rather than just shuffling them all back into the deck?
