At Stage 51 or above, when you duels SDS, some of them use broken decks. They use different cards than usual, and those cards looks holographic cards.
Stage 51 or above
The name of the deck does not make sense. Translated from JP into EN, it shows "There is no text."
They use very low stats monster cards, but these are holofoils.
This glitch is confirmed by some players.
Gearfried the Iron Knight
This glitch was confirmed by Papyrus and he kindly shared what he found with us. If you activate the spell card Exchange in a Legendary Duelist fight against Joey Wheeler and attempt to take his Gearfried (1800atk/1600def), the Attack and Defense would turn to 0, and there will be nothing in the description and name.
Destiny Draw (Skill)
Once the skill is activated the timer will continue to run out, however, once the timer reaches zero and your still on the selection screen or you still haven't choose a card you won't lose the duel unless you pick a card.
Found that out when dueling the lvl 51 gemini deck

I had a sergeant electro in defense position having disabled one of my opponent's facedown spell/trap cards, being attacked by a harpy lady and I couldn't use kuriboh to stop the attack. Cost me the duel.
there is a glitch with soul exchange using it to target there monster for tribute then using your enemy controllers second effect to take a diffrent monster from them you can use 2 of there monsters for a 1 tribute monster
Was it Summoned that turn? It only sends itself to the Grave on an End Phase that's on the same turn Gandora's Summoned: if something is done to have Gandora avoid that End Phase, it's safe on all other End Phases.
'Magician's Circle' won't triggered if 'Activation Confirmation' setting is set to 'Toggle Button' (regardless what setting is used, ON/Auto/OFF)
When I attempt to challenge the Vagabond and his rule is "No Monster Effects Activate." I put in cards like: Gaia Soul, Unfriendly Amazon, Flash Assailant... During the duel, Gaia Soul does not fade (hit the graveyard) at the end phase as his card effect states during this challenge. The challenge effect works on this card. However! When I send out Unfriendly Amazon, her effect still remains! At the start of my turn, if I do not have a monster on the field to tribute, she hits the graveyard. Her effect is still active! Glitch?
