Card Rulings:Butterfree

When choosing who must be under focus fire, the rules are as follows:

1. If you choose your rearguard to be attacked by all your opponent's units, then despite of the text "   until end of your opponent's turn.", if you allow your chosen rearguard to retire, then it will become "until end of battle" instead.

2. If you prefer you vanguard to be under attack, then your opponent cannot attack your front row rearguards unless your opponent's vanguard is other cards like Dragonic Kaiser Vermillion (or "THE BLOOD") or Exculpate the Blaster, since they have a skill that allows them to attack multiple opponent's units at once.
