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.

Monster like stratos still be able to active its eff even tho it got flipped. Unless the card say something like negate the summon, the activation, or effect, he still be able to active its effect. You probably notice that the effect can be activated as soon as he summoned, even before other card could react in general

After this trap resolves, can black rose dragon's effect turn them face up? Or is it straight up impossible to change their battle position.

You can still change their battle position through other effects. This card only affects the regular "you can change the battle position of a monster once per turn" rule.

I have a question: if I use this card with Magician Navigation what will happen?

I mean the two monster aren't summon at the same time: the first monster to be summoned is Dark Magician, from the hand, and the second monster is another spellcaster, from deck.

So, if we use floodgate, the only monster to be turned face down is Dark Magician while the other spellcaster monster is save. Am I right?

No, the last monster summoned will be flipped face down as you can’t active cards after a chain started resolving. If it was summoned on CL1 the one summoned from the deck is flipped face down, if it was summoned in CL2 then Floodgate Misses timing

Okay, this card has been a meta staple almost since the game’s launch. Time to limit so the op decks don’t have access to it.

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."

funciona com o flute of summoning dragon mas não funciona com os dois magos do mag. nav., nao sei por que

Porque os dois monstros não são invocados simultaneamente. O Mago Negro é invocado primeiro e depois o outro monstro, diferente da Flauta, que invoca dois dragões ao mesmo tempo.
now more people can abuse this op card

Floodgate Trap Hole cannot activate during the damage step
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.
