Increasing attack while lowering your opponent’s attack.
If you discard your cards and your Wonder Balloons get destroyed then it will be very difficult to make a comeback since you are left with only a few cards in your hand.
How to use this deck
It is recommended to not start by using Wonder Balloons and discard your hands early on against other players. Start by slowly decreasing their attack by discarding one at a time, this will prevent you from being vulnerable to getting your wonder balloons getting destroyed and left with a few cards.
Draw to discard:
Cards like Thunder Dragon can be used to draw more cards for you to discard, very useful for when you need an immediate decrease on the first or second turn. Chances of drawing a thunder dragon is also pretty high if you only put 20 cards.
Cont: If I go x sabers, i would also consider replacing mirror wall with Canadia/Hallucigenia, so I can also throw in generic level 5 synchros(X-Saber Wayne, Goyo Chaser) as well as Flamvell Uruquizas and Giganticastle, just cause there's space and they're possible.
Can Flash Assailant just be replaced with Jerry Beans Man or other high attack 4 star monsters?
2x Dweller In The Depths
3x Flash Assailant
1x Swift Gaia
1x Sword of Deep Seated
2x Shard of Greed
1x Pot of Dichotomy
Obviously you want to leave a spell slot open and use Twister when you need room. Having 2 PP and 2 WB almost guarantees one first hand. Ideally, you have one of each out. You can either A. Add a bunch of cards inc CoA and PoB and go for a trolly deck out. I'd also add 4star and TBD. Or B. Add SoI + Piranha + Secret Pass + GotM to not only troll but finish with a 9999 for extra salt.
