They cancel each other out. An attacker is not able to fulfill both conditions, therefore the attacking player can choose a defender as normal.
First, you attack with OPBL, then you flip the Battle Cards (including any Bold). If you flip a white battle icon, you flip two more Battle Cards. Then, you check if you have flipped an Action. You can play one of the actions. You will still get plus attack from the orange icons flipped on that Action.
Sergeant Chromias flip ability asks you to play a blue armor right then. If you dont, youve forfeited the opportunity to do so. Your normal upgrade play and action play arent affected by this. The flip ability does not allow playing Superior Plating without previously having played Tech Research.
In this scenario, Sturdy Armor would not give the extra +1 Defense as Optimus is not Ranged. Sturdy Armor is constantly checking for the enemys Ranged trait, all the way up until damage is dealt.
Tapped characters get KOd into the KO Area and are no longer tapped or untapped once in the KO Area. I Still Function! Returns the KOd character to the Battlefield untapped.
Thats correct. In this scenario you would be attacking for 4 with Pierce 6. Pierce stacks on Pierce, but not on regular attack damage.
Not quite. There are two errors in the scenario youre describing. The first is that Optimus trigger will resolve before damage is dealt to Lionizer. The second, is that your Optimus can only choose characters in your KO Area, so you would not be able to flip any characters in your opponents KO Area.
Yes, your opponent can attack with only one character.
If all of your opponents characters have already been tapped and you finish an attack with your untapped Combiner, you will then attack a second time with the Combiner.
The character they were attacking is part of your newly formed Combiner, so they are now attacking your Combiner.
No, it does not. Cards only affect cards in the KO Area if it is specifically stated in the card text.
You can choose someone else to nullify it.
In both scenarios, Spare Parts does not protect your weapon. A Battle Master or Weaponizer in weapon mode would go to KO rather than to your hand.
