Mommy's Sphere

(Disclaimer: Think slow but act quick. You should practice in PvE mode before stepping into PvP. If you feel like Ranked (300 sec) isn't enough, you can definitely make it on time while playing Casual within 480 sec time limit.)

It's time to feed your cat and care Melffy well. With proper treatment, it can be vicious and bring terror with C9. Without further ado, let's have a blast!

Gameplan

1) Place ME-PSY-YA on Pendulum Zone and Special Summon Chaos Emperor Dragon to find combo pieces from Banish Zone (BZ) with "Primal Seed" cards. Under no circumstance, don't banish either Formula or Ancient as LIGHT target for Chaos Emperor but you can banish any DARK target.

2) Link Summon Reprodocus and revive 2 x Formula with "Monster Reborn". Then, play "Temple of the Kings >>> DNA Surgery" combo to change the type of all monsters on the battlefield to Beast. This step is a must to XYZ Summon Melffy and its attachment ability. You are welcome to destroy Temple with MST, by the way.

3) XYZ Summon Melffy by using 2 x Formula as materials, pointing towards where Reprodocus is. You can start repeating these steps until you think it's enough...

• Your aim is to let Melffy have at least 10 materials. With "DNA Surgery" changing everything to Beast, you can attach anything.
• Since the attachment ability of Melffy isn't hard once per turn, it can be reset via Book spells.
• "Monster Reborn" can grant resources for Melffy.

4) Revive Ancient with "Monster Reborn" and place Xiangsheng on Pendulum Zone. With Xiangsheng, you can change the Rank of Melffy to 7 by targeting Ancient and Melffy.

5) Activate Reprodocus to change the attribute of Melffy to "LIGHT". Next, activate "Clockwork Night" to overwrite the type of all monsters on the battlefield to Machine. (Big thanks to Triki for type change tactics)

6) From Rank 2 EARTH Beast to Rank 7 LIGHT Machine, you can lead the way to C9. Start off with "Astral Force" to overlay into "Number 9" and then, C9 with "Barian's Force".

7) You can take off the pants of C9 and unload big amount of damage for the FTK.

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

- "Monster Reborn" is given for free, if you have played the tutorial to save 30 UR!

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

- "Into The Void" + "Allure of Darkness" can be found within "The Infinite Void" Secret Pack to save 180 SR!

- "Primal Seed" + "Pot of Acquistiveness" can be found within "Legacy Pack" to save 30 SR and 60 UR!

- "Wonder Wand" and "Spellbook of Knowledge" can be collected by purchasing "Spellbook of Prophecy" deck. 120 SR saved and you can try a new deck!

So, in total, you can save up to 630 SR and 120 UR, if you are willing to spend some gems. Other SR and UR cards I didn't mention are essential.

That's all for this one. If you have any questions, feel free to ask. Have fun in Master Duel!
