So I'm using this card against Arkana to block him from using his Dark Renewal on my final pirhanna summon (vs. lvl40), or using his Spell Shield when I try de-spell or Twister against his Ectoplasmer (vs. lvl30).
And I noticed a super interesting glitch -- Sometimes when playing this card, it actually shows me what his face down cards are !
It seems to only happen when I've already seen him play a card that he has multiple copies of. For example see this screenshot, I used a de-spell on his Anti-Magic Arrows, then several turns later use Xing to lock down 2/3 of his remaining face-down cards, and it SHOWS me that he put another Anti-Magic Arrows down, making it easy for me to just pick his other two cards. trolololol.
Also as a followup, I wonder if this card's effect lasts only while it remains on the field, or if it lingers after it is destroyed?
Because I had a match against Arkana that this got destroyed after using it, and he ended up never playing those cards I had locked down already. Technically the card does NOT say the effect is removed if the trap itself is removed from the field ....
That's not a bad thing...Anon seemingly talking in place of Andrew, especially if you only have 1 Ceasefire(possible last card dilemma) or no cards you can sac for the Discard. I always have 2; 1st catches whatever 2 cards it can immediately, 2nd locks the 3rd while relocking another. Oh yeah, you can overlap the locks.
