Step 1: Meh, but it's affordable.
Step 2: Hell yes!
Step 3: Okay, could get Rainbow Skillblooms for LC, but it's not an expensive deal, so waifu get an extra this week.
Step 4: Yes, perfect pricetag for a Rainbow Dressbloom!
Step 5: Still contemplating this step. Burning Bush is a very solid girl, not exceptional, but solid. And there aren't that many Pierce Rainbows with skill trigger. Hell, solid Pierce Rainbows are actually the ones that are hard to find!
