Mannadium of the Sinful Forest ft. Kashtira Scareclaw

An affordable Synchro deck with cards that can work in synergy with the white forest engine thanks to sheer number of spell cards.

Edited: I spent all day testing it out on Nexus and found this version to be the most consistent one (I took off the sinful spoils engine since it was rarely drawn; I also increased the number of mannadium cards adding some more hand-traps and board-breakers making this deck practical and functional). At the end I was able to fit a little Kashtira engine so to better disrupt the opponent field/extra deck by reducing the number of White forest cards that were too situational and the number of Reichhearts/Visas that could get easily revived by Dis Pater/Scareclaw Arrival: I also changed Mannadium Torrid with Mannadium Fearles so to have a better followup mixed with the effect to make Synchro Monsters stronger during the BP.

If someone has suggestions, I will gladly accept them!
