Yes, as long as it is Spell Speed 2 or 3, and Set on the field previously in the case of a Quickplay Spell or Trap card.
That means the opponent can potentially do something before you get your first opportunity to activate a spell speed 1 card or perform a summon.
This is the structure for a turn:
Draw phase
standby phase
main phase 1
battle phase
main phase 2
end phase
standby phase comes after your draw phase. nothing really happens here, it is just a phase for certain card effects to activate. if there is not an available effect to activate, you move on to you main phase 1.
Your Standby Phase is after your Draw Phase, but before your Main Phase 1.
Yes, it is a Continuous Trap card with a Quick Effect. You can activate the card in any phase of the opponent's turn, and you can activate the effect of the card in any phase of the opponent's turn also.
You can activate Windstorm of Etaqua during the battle phase in Yu-Gi-Oh. The card, Windstorm of Etaqua can not be activated during the damage step or after using a monster to attack your opponent in the battle phase.
Yes, of course. Trap Cards can be activated in the End Phase.
it depends only in special occasions like tower of Babel says each time a spell card is activate place 1 spell counter on it, so if you place this card down in your turn and then activate 1 spell card then tower of babel is activate immediately
If the opponent has no monsters in deck, or no monsters that Last Turn can special summon, then they just don't get a monster, nothing happens in the additional battle phase, and the opponent will probably lose in the end phase.
Since DD Sprite can only be summoned during your own turn, its trigger will activate in the opponent's Standby Phase.
Yes, you can chain to a card(s) that activate during the Standby Phase.
Even if the turn player makes no game actions (apart from his turn draw), he still has to pass Priority to his opponent each time he wants a phase to end. The opponent could activate his Royal Decree during any of these times, so, he could do it in the draw phase, standby phase, main phase 1, and end phase (the turn player can proceed straight from main phase 1 to the end phase. If the opponent did have a card that could only be used in the battle phase, here, he would not be given chance to use it).
Yes, it is a Continuous Trap card with a Quick Effect. You can activate the card in any phase of the opponent's turn, and you can activate the effect of the card in any phase of the opponent's turn also.
In your own standby phase, yeah. It is a Quickplay spell, so can be played from hand in your own turn. You can draw it, then activate it in the Standby phase, tributing Treeborn Frog, then resummon the frog before the standby phase ends.
You can activate Windstorm of Etaqua during the battle phase in Yu-Gi-Oh. The card, Windstorm of Etaqua can not be activated during the damage step or after using a monster to attack your opponent in the battle phase.
Yes, as long as it's your own turn. If you want to activate them in the opponent's turn, you need to have Set them on the field during your own.
Yes, of course. Trap Cards can be activated in the End Phase.
Standby phase is in a yugioh duel after draw phase,you could use card effect at standby phase.
Magical hats can only be used during your opponent's battle phase. Seeing as they can't flip their monsters during their battle phase, no. However, if your opponent does activate a spell or trap card during the battle phase, you can use Magical hats and protect your monsters. Overall, yes. You can use magical hats to protect your monsters from targeting effects as long as it's during your opponent's battle phase.
it depends only in special occasions like tower of Babel says each time a spell card is activate place 1 spell counter on it, so if you place this card down in your turn and then activate 1 spell card then tower of babel is activate immediately
You can only do so in your turn. You may do so during Main Phase like a normal Spell Card. You can also do so to start a Chain. For example, if your monster attacked and your opponent activated Mirror Force, you can Chain My Body as a Shield from your hand. If you plan to activate a Quick-play Spell Card during your opponent's turn, however, you must Set your Quick-play Spell Card during your Main Phase.
