If you mean level limit area B, then no, it will immediately be changed to DEF if it is LV 4 or up.
The core rules state that a Normal Summon places the monster in face-up Attack position, and a Set places it in face-down Defense position. Special Summons are face-up Attack or Defense position, unless stated otherwise. If the continuous Trap card 'Light of Intervention' is active, monsters can be Normal Summoned in face-up Defense position.
If you switch it from attack position to defence position you can't because no monster can attack from defence position except from "Total defence shogun". But if you switch it from defence position to attack position then you can attack
yes, but only monster cards. you can special summon it in face-up defense or attack position.
yes
As long as you are Special Summoning before, or during the Battle Phase, then yes, that monster can attack.
Unless another card specifically denies the attack or if it was Special Summoned AFTER the Battle Phase, then yes the Special Summoned monster may attack.
You cannot tribute summon a monster in face up defense position. You can either tribute summon a monster in face down defense or face up attack position. If you want to summon in face up defense, you need to special summon.
It depends.If the Monster declares an attack or already attacked and it is switched to defense position by a card effect (like Enemy Controller or Book of Moon for example) the Monster's position cannot be changed by you, the controller, because it declared an attack already. A Monster's position cannot be changed by their controller for the rest of a turn after they declared attacked with it.If the Monster did not attack yet this turn and their position is changed due to a card effect, it can be changed by the controller.
Yes. If your monster is in attack position and you attack a monster that has more attack points than yours, your monster is destroyed and you take Battle Damage to your Life Points equal to the difference between your opponent's monster's Attack Points and your monster's Attack Points.
Assuming the defending monster is also in attack position, both monsters will be destroyed.
A Normal Summon is face-up attack mode, a regular Set is face-down defence mode. You cannot Normal Summon or Flip Summon into face-up defence position unless an effect like Light of Intervention lets/makes you. Unless specified though, a Special Summon can be face-up attack or face-up defence position. However you can't special summon face-down unless an effect lets/makes you.
Only the Spell card Darkness Approaches can flip a monster into face-down Attack position. By discarding two cards, Darkness Approaches lets you flip one face-up monster face-down without changing the battle position (so a monster may end up in face-down Attack position).
