1) If attack has within its description (like Parker Barrows Six-Shooters), will it work? 2) If model has global to Attacks (like Sabertooth Cerberus with 5+ wounds remaining), will it work? 3) Can focus and soulstones be used to get on disengaging strikes?

Greetings! I have a question about a bit stupid situation. Let's say we have the Eternal Flame and a model without burning condition. The Eternal Flame tries to use its Flaming Detonation attack on the other model. Flaming Detonation (Ca 6 / Rst: Df / Rg: 10): Target model with the Burning Condition immediately resolves the Burning Condition as if it were the end of the Turn. Is targeting a model without the Burning condition with this attack illegal and can not be declared or it could be targeted and attacked but as the model has no Burning condition it will do nothing? Another example: targeting non-friendly model with any "Target friendly model..." action. Is it illegal to declare or just having no effect?

Actually my situation is silly in the first place. I wonder if it is allowed by rules to take second Disciple action as action caused by the first Disciple action...

Here is Disciple ability wording: (0) Disciple (Ca 6 / TN11): This model immediately takes a (0) Action belonging to a friendly Leader in play. Any cards which this model would discard during the course of the Action are shuffled into its deck after completing the Action. One of local players told me that Yu would not be able to use this ability within itself because of core zero ap action rule stating "A model may take only one of these “free” Actions per Activation". Is he correct? Just in case I want to say that my question was theoretical and this situation shall not see tournament play and most likely non-tournament play too. I'm just curious about how rules work and if there is some rule that hadles loops.

I want to ask about a very specific situation. It may have no sense but I am curious about the way rules work. We play a 40 soulstone game so Henchman can be taken as the leader. I choose Sensei Yu as leader with Recalled Training upgrade attached, hire Hannah as a mercenary for her Arcane Reservoir +1, take someone else with Equality and whatever else to spend soulstones. During one of my turns I have black joker, all aces and two deuce. I allow my enemy to score some VP during the turn to get a card from the Equality upgrade and it is another deuce. Then I activate my Sensei Yu, discard his Recalled Training upgrade to get +flip on all fips for the remainder of this turn, move him to within 2" of an Ancient monument in order to get +2 Ca to all Ca actions and use Yu's Disciple ability. The only card in the deck that causes Yu not to reach TN is a single deuce and he has +flip. He casts the Disciple ability that makes him immediately take a (0) action belonging to a friendly leader in play. The only friendly leader (0) action is the Disciple. Will Yu be able to take Disciple ability again this way? If no, why not? If yes, what will happen if each time deuce comes I take other card because of +flip and I do not cheat a card from my hand?
