After figuring it out, Ree Shil reluctantly clicked the surrender button.
Hum!
His vision blurred, and he appeared in the Pure White Space.
What he had just done, lacked a crucial point.
First of all, to defeat this Boss, there was no doubt that [Flying Sword Immortal] was the best choice to perform DPS behind enemy lines.
But once it left, he lost an outer card to take [Cloud Capturing Skill].
This would result in the row of cards originally behind [Flying Sword Immortal] being wiped out by [Doombringer] in a few rounds.
In a Boss battle with both DPS and survival pressure, not a single card could be spared.
If casualties occurred, the best outcome would be that the other cards would not die while maintaining the formation, but due to insufficient DPS, there would be no chance to perform damage before the Boss used the skill [Resurrection].
