"Let's start with a preview."
Ree Shil carried out a preview of [Mechanical Valley Witch] and [Golden Heavenly Jade], and the result was feasible.
This would turn [Mechanical Valley Witch] into a C-Class gold-edged card.
"I won't make the gold edge just yet; I need to first turn [Mechanical Valley Witch] into a B-Class card."
So he looked over the batch processing results once more.
"Tsk... even the preview results for turning it into a B-Class card aren't that great in terms of quality and strength."
"Wait, something's wrong."
Suddenly, Ree Shil realized that he had overlooked something.
Doesn't he have multiple [Mechanical Valley Witches]? He hadn't previewed the result of them combining cards with each other yet.
So he did another round of previewing, and sure enough, something came out.
[Mechanical Valley Witch] + [Mechanical Valley Witch] = [Mechanical Valley Witch]
The name hasn't changed, and the projection hasn't changed.
But the grade has changed.
