Monster
Mash is the first deck I seriously play tested with the formats having
Spellcasters dominate the meta with Dark Liberation. I first discovered the
potential of a Monster Mash build when Royal Demons first came out and people
were running Spells like [Hammer Crush] & [Beast Gear World] that did not
do much to help with bringing out the full potential that Royal Demons have. As
I play tested more with different variants of Monster Mash, I discovered that
the addition of [King Rex] and [Megazowler] gave Royal Demons more ways to
approach an established board. I quickly began to realize that King Rex
widening the board was the start of how aggressive you can go with a deck full
of monsters. This led to the addition of [Phoenix Dragon] and [Rush Dragon
Dragears]to have more lines of play to work with. This
leads to Monster Mash’s matchup spread beat over everything with the
Spellcaster matchup being a 50/50 depending on how well you can use [Wicked
Shadow – Dark Rooker] with your hand.
After a lot of playtesting against multiple matchups
including Spellcasters, I settled on this build because of how capable it was to explode aggressively with the Royal Demon, King Rex, Dragon, and Rooker packages.
It gives you multiple lines of play in a single turn with its capability to
clear boards, widen the board, or remove backrow. I want to showcase some of
the card choices here that have made this deck a top contender in today’s meta.
This article will cover the basic idea of Monster Mash and how weaker engines work together to form a strong unit.
Monster Mash Deck List
Engines
Dinosaur Engine:
2 Megazowler
3 Mammoth Graveyard
3 Little D
3 Super King Rex
Special summoning in Yu-Gi-Oh will always be good. Being able to widen our board gives us more things to do with our turns. While Graveyard Mammoth and Little D may have low impact on the board, they do have power by just being Dinosaurs to make King Rex's effect live as soon as turn 1. It is important to know that this is a tradeoff of power for consistency, but King Rex brings an increase in power with better board set up. Some builds run less than 6 low level Dinosaurs for low level monsters like Whispering Fairy, but there's the tradeoff of having to possibly take more turns to set up King Rex. Power can be viewed as the impact of a play and consistency can be seen as the rate of how we bring that power over to the board. An increase in power comes with a decrease in consistency and an increase in consistency comes with a decrease in power. It is important to know this when it comes to building a deck that is all about summoning monsters.
Our focus with this build is being consistent and powerful and that is where other engines come in to cover what the other engine has lost in either power or consistency. Megazowler has power by also being a Dinosaur for King Rex. Summoning a free level 6 Megazowler is what brings out the strength of Royal Demon's Death Voice and Heavymetal.
Royal Demon Engine:
3 Royal Demon's Heavymetal
3 Royal Demon's Death Voice
3 Royal Demon's Punk
3 Gargoyle of the Palace
The Royal Demon package is where our most of our removal and power comes from. Royal Demon's Death Voice and Heavymetal benefit from the Dinosaur package along with the Rooker engine providing extra tribute fodder. Having cards like Set/Upsetter/Kuribot allows Royal Demon's Punk to become powerful in providing 2 monsters on board to be used by what Punk brings back from the GY. Death Voice's effect with its 1800 ATK stats make it powerful enough to destroy any monster in the game currently. Death Voice & Punk gives the deck a way to not get overpowered by Fiendish Commander Yameruler.
Rooker Combo Engine:
3 Dragon's Setupper
3 Dragon's Upsetter
3 Kuribot
2Wicked Shadow - Dark Rooker
The Rooker combo is an engine that gives the deck full of monsters the only way to deal with backrow. It brings an incredible amount of burn damage that fits well with the deck that pushes big damage with Heavymetal and King Rex. Set/Upsetter/Kuribot works well with our low level monsters to be able to destroy 2-3 backrow in a single turn. Most of the time the combo will end with Rooker being set facedown or back in the hand for future plays. A set Rooker has proven to be powerful with it's incredible 2600 DEF stats that most monsters cannot get over without it being face-up making it a powerful turn 1 play.
Combos
Combo 1 with Death Voice
1. Normal Summon Mammoth Graveyard and Gargoyle of the Palace(Any low level monster).
2. Tribute both Mammoth Graveyard and Gargoyle of the Palace for Super King Rex.
3. King Rex's effect, mill 1 to Special Summon Megazowler from the GY.
4. Tribute Megazowler for Royal Demon's Death Voice that is now active to use on the opponent's board.
Combo 1 with Heavymetal
1. Normal Summon Mammoth Graveyard and Gargoyle of the Palace (Any low level monster).
2. Tribute both Mammoth Graveyard and Gargoyle of the Palace for Super King Rex.
3. King Rex's effect, mill 1 to Special Summon Megazowler from the GY.
4. Normal Summon any low level monster(Dragon's Setupper), and tribute both Megazowler & Dragon's Setupper for Royal Demon's Heavymetal with an active effect. Bringing 7500 Damage on the board.
(Note: If you don't have Megazowler or any other level 5+ to be able to summon on the board, Super King Rex with tribute fodder will act as that level 5+ for Heavymetal's effect)
Combo 2: Rooker Combo
(Note#1: Dragon Set/Upsetter/Kuribot all act the same way when comboing with Rooker, so I will be showing just Dragon's Setupper)
(Note#2: The amount of S/T destroyed in this combo equals the amount of other normal summons in your hand with possibly 1 more S/T destroyed)(This combo shown will be using 2 other low level Normal Summons in hand)
1. Normal Summon Dragon's Setupper with Dragon's Upsetter in the GY, and use Setupper's effect to Special Summon Upsetter from the GY.
2. Normal Summon a low level monster and tribute Dragon's Setupper + Low Level Monster for Wicked Shadow - Dark Rooker.
3. Dark Rooker's effect to mill 1 and destroy 1 Spell/Trap, and returning back to the hand.
4. The board is now just Dragon's Upsetter which has not used it's effect yet, so Dragon's Upsetter effect to summon back Dragon's Setupper.
5. Summon another low level monster and tribute Dragon's Upsetter + Low Level Monster for Dark Rooker again.
6. Dark Rooker's effect to mill 1 and destroy 1 Spell/Trap, and returning back to the hand. With a new Dragon's Setupper on the board alone, Dragon's Setupper effect to summon back Dragon's Upsetter.
7. This is where you have a couple of options to play with. You have the option of Tribute Summoning Dark Rooker for the 3rd S/T removal, tribute setting Dark Rooker for the next turn of looping, or tribute summoning another high level monster from hand with set/upsetter.
Conclusion
These were the basic combos of what Monster Mash can do with other engines.
Combo 1 shows how Super King Rex correlates with Royal Demons and how it widens the board to produce more powerful options to end with on the board.
Combo 2 shows the Dark Rooker Combo which shows how a deck full of monsters can still have removal for the opponent's backrow while also accumulating a number of damage from it.
Card Destruction is a new legend that is being tested, but has proven to be really powerful. Being able to dump our Megazowlers, Set/Upsetter/Kuribots to fuel the graveyard has shown combo potential and a consistency boost. Other Legend cards like Summoned Skull that works with Royal Demon's Punk and Trap Hole are currently being tested.
This is a very strong deck that is a strong contender with the current top meta decks. The Spellcaster matchup is pretty even as long as you have access to Dark Rooker, or winning early on by overpowering the board with cards like Super King Rex and Heavymetal.
A video on Monster Mash has been published before which shows the power of these combos:
