Cyber Dragon Zwei gains a 300 ATK bonus during the Damage Step only, in a battle when it is the attacking monster. As soon as you leave the damage step, it loses the bonus.
No, it doesn't end the battle phase.
Yes, Stardust Dragon can activate its negation Quick Effect in the Battle Phase, and even the Damage Step.
No, Cyber End Dragon cannot attack three times on its own. It can normally attack only once per Battle Phase unless another card effect allows it to attack multiple times. To attack three times, you would need to use support cards like Limiter Removal, Power Bond, or Card effects that grant extra attacks, such as Twin Swords of Flashing Light - Tryce or Double Attack.
AnswerYes. He attacks on the saame turn he is special summoned because it is still the battle phase.This is also the case for Cyber Jar. When the Cyber Jar effect resolves the monsters that you special summon in attack position can still attack because you are still in the battle phase.
Your opponent's next attack is the next time that player declares an attack in the battle phase. Basically the first attack the opponent declares will automatically be negated.
Standby phase is in a yugioh duel after draw phase,you could use card effect at standby phase.
Yes, of course. There's no reason to think he can only attack monsters that were present at the beginning of the battle phase, or before his first attack is declared. If monsters are summoned during the same battle phase, by any effect, he may attack them.
No, if it leaves the field, it is unable to Set itself during the end phase. It must survive whatever battle it is involved in, and remain on the field.
No, the battle phase ends on resolution. The attack in question will be cancelled as the turn has changed to a step where attacks cannot be declared.
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.
Yes, Battle Fader's effect is a trigger, activated in hand when an opponent's monster declares an attack. Light and Darkness Dragon will chain to and negate this, meaning Battle Fader is not summoned and the battle phase does not end. Note that Light and Darkness Dragon does not destroy the cards it negates, so Battle Fader will remain in hand. It can be activated again when the next attack is declared.
their really isn't a big difference between them except for the fact in Main Phase 2 you can't attack again if you are planning on setting Spell [S]/ Trap [T] cards face-up or face-down. what i mean is - Draw Phase - Main Phase 1 - Battle Phase - Main Phase 2 - End Phase during Main Phase 1 you can set your s/t cards and launch you attack in your battle phase. Main Phase 2 if you can set more s/t cards after your done setting the amount you want to set you'll probably have to end your turn.
