Apple Bride looks like a top tier support, definitely add her to my wishlist, she's pretty much similar as my Bluet (Rising Star of the Sparkling Fairyland), one of my best supports.

I kinda want to go the brute-force route because this route is kinda fun to me, I like the summon mechanic.

So far I tried Sigilaria a lot and I think the differences between being able to summon or not being able to is pretty huge, but to get enough skill activation rate and act again is my current problem, should I just go ahead and max out her skill with my Skill Flowers ? I think Skill Flower is pretty easy to get so I just want to spend them without thinking, somehow even with decent skill activation rate she just doesn't want to use her skill.

I'll continue to search the wiki more to find if there's even a unit with Turn 1 Skill activation + Turn 1 Act Again, with a great turn 1 Sigilaria can keep her summon forever, that's the real good thing about her.
