You cannot manually. Such an occurence could only result from a card effect.
They 'can' attack directly, meaning they are free to attack the opponent's monsters instead if you wish.
Patrician of Darkness only allows you to choose the target monster of your opponent's attack. It does not make you attack another monster on your field.If you have multiple monsters on the field in addition to Patrician of Darkness, you can choose which of your monsters that your opponent must target when he or she attacks.
Toon Monsters can attack directly if the opponent has no Toons, but if he does have one, the turn player's Toon must attack it (if he attacks at all, that is). No other part of the show's Toon rules are applied. The Toon controller's life points are not protected in any way. A player's non-Toon may freely attack the other player's Toons or non-Toons, and damage calculation will proceed as normal. If the Toon Monster is too strong, then you will need to destroy it with an effect first. A monster that can attack directly, can do so even if the other player has a Toon monster. Toon Monsters do not interact in any way with direct damage, so cannot stop burn damage from cards like Chain Burn.
Lord of D. cannot stop cards that DO NOT TARGET. As it would be unreasonable to list every card that can achieve this, the cards listed below would be some examples:Mirror ForceTRAP/NormalActivate only when an opponent's monster declares an attack. Destroy all Attack Position monsters your opponent controls.Torrential TributeTRAP/NormalActivate only when a monster is Summoned. Destroy all monsters on the field.FissureSPELL/NormalDestory 1 face-up monster your opponent controls that has the lowest ATK. (If it's a tie, you get to choose.)Smashing GroundSPELL/NormalDestroy the 1 face-up monster your opponent controls that has the highest DEF. (If it's a tie, you get to choose.)RaigekiSPELL/NormalDestroy all monsters on your opponent's side of the field.
There are two different "kinds" of Toon monsters that behave slightly differently. The newer Toon monsters state the following:While you control "Toon World" and your opponent controls no Toon Monsters, this card can attack your opponent directly.So as long as you control "Toon World", a Toon monster can attack your opponent directly even if they control monsters.However, the older Toon monsters and "Manga Ryu-Ran" state:This card can only be Special Summoned while you control "Toon World". ...When "Toon World" is destroyed, destroy this card. If your opponent doesn't control a Toon Monster, this card can attack your opponent directly. If your opponent controls a face-up Toon Monster, you must select it as an attack target.Unlike the newer Toon monsters, these monsters can attack directly even if "Toon World" is not on the field. This is because if "Toon World" is removed from the field other than by being destroyed (returned to your hand, returned to your deck, etc.), your Toon monsters will not be destroyed as well. And since there is no requirement for "Toon World" to be activate so they can direct attack, they can do just that.
NO it can't destroy monsters however, venom swamp can destroy monsters if their attack points are 500 points or less it becomes 0.
Of course not. You cannot declare an attack on the opponent's lifepoints if they have a monster, unless one of your monsters has an effect that allows it to attack directly.You'll just have to deal with their monster using Spells or Traps, a monster effect, or by boosting the ATK of one of your monsters.
They 'can' attack directly, meaning they are free to attack the opponent's monsters instead if you wish.
Assuming the defending monster is also in attack position, both monsters will be destroyed.
Yes, but you have to attack one at a time. Now if your talking about attack one monster with all your monsters the answer is no.
If this card attacks a defense position monster your opponent controls, destroy all defense position monsters your opponent controls after damage calculation. During your end phase, destroy all of your monsters that did not declare an attack this turn.
Ra's attack and defence is equal to the combined attack and defence of the monsters tributed for its summon. You can also tribute other monsters to increase Ra's attack and defence by that monster. When Ra is summoned from the graveyard (monster reborn etc.) it has 0 attack and defence as no monsters were tributed for it
He has 4000 attack power. His effect is you discard two monsters you destroy all monsters on your opponent side of the field.
Patrician of Darkness only allows you to choose the target monster of your opponent's attack. It does not make you attack another monster on your field.If you have multiple monsters on the field in addition to Patrician of Darkness, you can choose which of your monsters that your opponent must target when he or she attacks.
Yes, two Malefic monsters can attack on the same turn, but this is a rare situation considering all Malefic monsters state, There can only be 1 face-up "Malefic" monster on the field, and a couple also say, Other monsters you control cannot declare an attack.However, if you were to somehow attack with one Malefic monster, remove it from the field, and summon another one, the second Malefic monster will be able to attack.
1 Tuner + 1 or more non-Tuner monsters If this card attacks a Defense Position monster your opponent controls, destroy all Defense Position monsters your opponent controls after damage calculation. During your End Phase, destroy all other monsters you control that did not declare an attack this turn.
If you're talking about monster zone 'columns', then these have nothing to do with attack declarations. A monster on one player's side of the field is able to attack the monsters on the opponent's field, regardless of which column they are in.
