Diabolic Assault

Danger in the soaring skies! A diabolic dragon is willing to assault your opponent with an angel. Interesting, huh?

Gameplan

1) Plant a flower to opposing side with "Black Garden". Then, Synchro Summon Assault Dragon by using Accel + Formula as materials.

2) Synchro Summon Cupid by using Shamisen + Exodia/Idol as materials and reduce the level of Cupid by 3.

3) Special Summon Shamisen with its ability by shuffling Formula back into Extra Deck. Then, Synchro Summon Beelze by using Librarian + Shamisen as materials and pass Beelze to opponent by destroying the flower while replacing it with "Mystic Box".

4) Synchro Summon Formula by using Exodia/Idol + Cupid as materials.

5) What is going to happen is as follows:

1. Cupid deals damage.
2. Beelze gains ATK, which is mandatory and not hard once per turn.
3. Assault Dragon deals damage because opponent activated monster effect, which is Beelze. Assault Dragon's effect isn't also hard once per turn.
4. First, action in #2 happens. Then, #3 happens. It's mandatory endless loop, until someone dies.

If you wonder how to save up some SR and UR points, I can show you:

- "Pot of Avarice" can be collected by purchasing "Re-Contact Universe" deck. 90 SR saved and you can try a new deck!

- "Black-Winged Assault Dragon" can be collected by purchasing "Blackwing's Pride" deck. 30 UR saved and you can try a new deck!
