It Works by abusing the Frightfur Engine and the Shaddoll Engine along with new support to make use of Cost Friendly Fusion Summons, easily allowing an OTK.
This deck can also abuse Super Polymerization, which makes it better against aggro decks, it also uses Instant Fusion as a enabler for a quick Dragostapelia.
There is an easy combo that starts with only one Ophrys Scorpio and another monster on hand, which leads to Winda Lock, Special Darlingtonia via Ophrys, add Instant Fusion, make Cherubini, then go for Winda via Instant Fusion.
The Predaplant core itself is kinda heavy but Consistent, with 3 Ophrys and 3 Lonefire you have a Consistency ratio of around 55%, not counting the triple Predapractice.
It can also end on the StapeliaPlanning combo, which is basically Predaplant Dragostapelia with a Predaplanning Set.
I did cut Predaplast off because i've seen it on my hand doing absolutely nothing too many times, it may prove useful in a future build but not now.
