Monster Zone Lock

You can possibly lock your opponent's monster zone if he/she has no tribute monsters. Use Floodgate Trap Hole when your opponent Summons a Monster. Then disable the 2 remaining zones by using Ojama Knight's effect. You can then wait to get the cards that you needed or burn your opponent.


The text "monster(s)" on Floodgate Trap Hole means that it can affect multiple cards. See these screenshots below for example.

The opponent used The Flute of Summoning Dragon to Special Summon 2 Blue-Eyes White Dragon on the field. Then the Floodgate Trap Hole prompt pops up.

Floodgate Trap Hole is Activated.

Both of the Blue-Eyes White Dragon has been switched to face-down defense position.

Tenho uma dúvida!
Por que a Floodgate Trap Hole não se ativar após a resposta do Navegation Magician?
Lembrando que efeito da Navegation que "Invoque um Mago Negro na mão e feito isso chame mais um mago inferior ou igual do deck por campo."

I've an issue with this card. The card effect description applies to 'monster(s)' as it can be one monster or multiple monsters. Back then when I dueled, it apply to 2 Dark Magician via Magician Navigation. Now only apply to last summoned monster.
Is there a new rule changing?
I hate this card.

IF you main a red-eyes deck with slash and A/D changer, or a neos fusion deck with A/D changer, you could banish it and flip your slash back up.

This Trap is very popular.
Something weird happens against desperado... I'm not entirely sure if it works.

So I found out the hard way that Subterrors can get around the effect of this card by using their Final Battle trap card and flipping their monster face-up again, even though that seems like a ruling issue since their changing the battle position of their monster.
Is that incorrect or am I crazy?

It was always like that and not only with Subterrors

"Monsters cannot change their battle positions" is a active form, so it means monsters cannot change their battle positions BY THEMSELVES.
If you use card effects to change their positions, it still works.

Also, if you attack into them, they would be flipped face-up, by game mechanic.

If the floodgated monster is flipped face-up due to being targeted for an attack, and it survives the attack, it then can change its battle position, as FTH's "no position change" part specifies that the monster has to be face-down.
never gets old, ever lasting trap
Enemy summoned Aromage Bergamot. I activated Floodgate Trap Hole. He/she activated Aroma Garden. Their monsters gained ATK, etc. So Aroma Garden resolved mormally. Then the newly summoned monster didnt changed into facedown def pos. No "canceled card effect animation or whatsoever. My trap hole simply ignored and sent to the graveyard. Is this how this should work? Or how can I contact Konami?

Then that answers your question- Bergamot is unaffected by trap effects the turn it’s summoned by Rose Lover

Oh crap... You're right. I'm using this card (Rose Lover) as well, since a year now or so, and I didn't notice it. Sorry for spamming.
