  • The affected monster can't change its battle position.


  • None.


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.

*sees card* hmmmm
I was facing anki deck , they activate mask change , summon anki and I wasn’t able to activate floodgate , question didn’t pop up , then they activate another mask change and summon another anki then the question was popped up for me to use floodgate. So my question is why couldn’t I use floodgate on the first anki ???

Floodgate Trap Hole can only be activated if the last thing to happen was a Summon. Which wasn't the case here. (I'd guess they chained Mask Change to something.)
How is this possible?

Yeah, FTH's description is not clear. It actually only stops you from manually changing the position. Any other card effect can still change the monster's position. Heck, even just attacking the face-down monster, removes that restriction, which is why attacking a monster flipped face-down by FTH is a bad idea unless you can destroy it with that attack.
Lol. I use to buy packs ten by ten. Today I bought my first ten Generation Next packs and this little bastard poped up on 2nd pack xD

RIP reactor dragon
The point is those metas use it alot, don't tell me bs using it for anti meta.
Use this to lock an ancient gear reactor dragon and see 2 out of 3 players rage quit
Love this card.
Two of these,
Two Canadia
Two Offerings of the Doomed
Two spheres

These pretty much form the backbone of all my decks. I have found that regardless of the meta, which changes so quickly due to the new releases, I am in with a fighting chance.

Its sure unhealthy for the game in 3 card slot monster format, canadia is healthier than floodgate cause its doesn't clog and the game became stall
This or canadia

Canadia is generally more useful as you can activate it during the battle phase,and his second effect is pretty neat for Synchro or Tribute fodder.

Floodgate works better in Stall/Burn decks and against decks that special summon more than one monsters (Like what was shown in the example gallery since it can shut down more than one monsters).

I'd go with Canadia. It's more versatile as it isn't only limited to special summoning or regular summoning. You could use it in the battle phase too.
What will happen if you chain Mask Change to Floodgate? Will my Anki be flipped facedown? Or the monster that I summoned first?

anki will not get floodgated and your 1st monster will be sent to the GY

Yeah because the targeted monster was the first one. Since it's chained the trap loses it's target
Tbh this card is too OP for dl, its has potential to play stall by clogging all monster zone, alongside with canadia basically you have 6 card that can clog thier monster zone
