Okay, my friend and I have just started playing so i have a question about that card. Trust Your Feelings,

Enhance a Character Unit

Action: Focus this enhancement to remove 1 focus from enhanced unit

Now, say it's on Yoda, can I focus to attack THEN focus Trust Your Feelings so that I can focus Yoda to strike again effectively attacking twice.

Yes you could. But it's still essentially one attack. He just strikes twice during it
