I'm sure that for newbies, after experiencing Master Duel, they will inevitably panic when there are cases where the effects of monsters cannot be used temporarily. So, let YGO Vietnam help you!
Master Duel: Rule Book: Part 4: Better understand the "Forgetting" phenomenon of cards - Master Duel
overview
Once a monster has been Summoned, it begins to carry all sorts of information, such as:
- Its Summon Time.
- How exactly was it Summoned?
- The effects are applied to it.
- Etc
If the monster is temporarily face down
If your monster is temporarily face-down (under the effects of Book of Moon or Subterror), it will forget:
- Any properties that the cards used to Summon (Tribute, use materials, special summon, etc.) have at the time of Summon.
- Any effects previously applied.
However, it will not forget :
- Which specific cards were used to Summon it.
- Whether it is Special Summoned or not.
- Whether it is Summoned that turn or not.
Naturia Bamboo Shoot (Example 1)
EARTH
5Naturia Bamboo Shoot
ATK:
2000
DEF:
2000
If this card is Tribute Summoned by Tributing a "Naturia" monster, while this card remains face-up on the field, your opponent cannot activate Spell or Trap Cards.
If face-down , Naturia Bamboo Shoot will forget whether or not it Tribute Summoned a Naturia Monster. From there, its continuing effect will be interrupted .
Onslaught of the Fire Kings (Example 2)
Spell
NormalOnslaught of the Fire Kings
If your opponent controls a monster and you control no monsters: Special Summon 1 FIRE Beast, Beast-Warrior, or Winged Beast monster from your Deck. Its effects are negated, also it is destroyed during the End Phase. You can only activate 1 "Onslaught of the Fire Kings" per turn.
From there, some monsters will receive some benefits , such as: Monsters Summoned by Onslaught of the Fire Kings will not be destroyed if they are face-down and then turned face-up before the End Phase.
Stardust Dragon and De-Synchro (Example 3)
WIND
8Stardust Dragon
ATK:
2500
DEF:
2000
1 Tuner + 1+ non-Tuner monsters When a card or effect is activated that would destroy a card(s) on the field (Quick Effect): You can Tribute this card; negate the activation, and if you do, destroy it. During the End Phase, if this effect was activated this turn (and was not negated): You can Special Summon this card from your GY.
Spell
NormalDe-Synchro
Target 1 Synchro Monster on the field; return that target to the Extra Deck, then, if all of the monsters that were used for the Synchro Summon of that monster are in your GY, you can Special Summon all of them.
Another example of not being affected by being flipped face down :
- If a Stardust Dragon is turned face down, then face up, and is targeted by De-Synchro , you can still Special Summon its summoning materials.
Obelisk the Tormentor (Example 4)
DIVINE

Spell
