The reason why fusion monsters have a hard time being relevant in the meta is because of all the resources that are needed, and in the end the fusion monsters often can be removed easily by your opponent. That’s why fusion monsters need a very strong effect to make them worth it to bring out.
Red-Eyes Slash Dragon fortunately has access to such an effect. Another reason why it can actually be worth it to bring out Red-Eyes Slash Dragon is because he can be special summoned again by the effect of Red-Eyes Wyvern and Red-Eyes Spirit once he gets destroyed.
Multiple versions of a Red-Eyes Slash Dragon deck can be played, there is room for a lot of creativity. If you are missing certain cards (for example Elemental Hero Blazeman) you can try a different version that uses different Warrior type monsters.
The first version with Elemental Hero Blazeman is able to bring out Red-Eyes Slash Dragon much faster than the second version. The second version however leaves room to decide which fusion monster you want to bring out depending on the situation (Sky Galloping Gaia or Red-Eyes Slash Dragon), also with the second version when Red-Eyes Slash dragon dies you can bring out a stronger warrior monster.
The strength of this monster comes from the fact that whenever a Red-Eyes monster attacks (this can be a Red-Eyes Wyvern, Red-Eyes Black Dragon, Red-Eyes Slash Dragon or this also counts when your opponent attacks with a Red-Eyes monster), you can equip a warrior monster from your graveyard to a Red-Eyes monster and it will gain 200 attack, also whenever a card you control is targeted by a card/effect you can send 1 equip card to the graveyard to negate and destroy that card. For example if you attack with your Red-Eyes Slash Dragon into a Man-Eater Bug, you can remove the warrior that you equipped to this card during the attack declaration, to negate Man-Eater Bug’s effect so that your Red-Eyes Slash Dragon survives. But its effect doesn’t end there, if your Red-Eyes Slash Dragon would be destroyed (for example by running into a Mirror Wall/Super Rush Headlong) you can special summon as many warrior monsters that were equipped to it as possible.
So not only does this card have a built-in way to protect itself, it also brings back monsters when it’s destroyed (as to not leave your field defenseless).
Pro tip: if you are playing against this card and you want to use Enemy Controller on it to stop its attack, put your toggle to “ON” so that you can use it at the start of the Battle Phase, if you leave it on “AUTO” you will only get a prompt once Red-Eyes Slash Dragon declares an attack, at which point it’s too late.
Besides being a warrior type monster, this card draws a polymerization from your deck when normal or special summoned, so having this card and Red-Eyes Black Dragon in your hand means you can summon Red-Eyes Slash Dragon.
Don’t forget if your Red-Eyes Slash Dragon is destroyed with this card equipped to it, you can special summon it and draw another Polymerization.
Storm is already a great backrow removal card in Red-Eyes Zombie Dragon decks, and it works well with this deck for the same reasons; you can chain your Red-Eyes Spirit to it to get both effects and also allows you to get rid of dead cards like Red-Eyes Insight (once you can’t use it anymore). In the Sky Galloping version it also synergizes well with Gateway to Chaos and Spiral Spear Strike.
You can also use it when there are warrior monsters equipped to your Red-Eyes Slash Dragon if you want to clear some backrow or if your spell/trap card zone is getting clogged up.
The reason you might want to run this card is that when it’s equipped to your Red-Eyes Slash Dragon and it’s destroyed, you can special summon Guardian of Felgrand from your graveyard and equip Red-Eyes Black Dragon or Red-Eyes Slash Dragon to it and raise its attack to 1700/1900 respectively. Another reason to use this card is that if you tribute this card together with another monster you can special summon a level 7 or 8 Dragon from your graveyard, meaning you can bring back your Red-Eyes Black Dragon or Red-Eyes Slash Dragon with its effect as well.
Both these cards are included for the same reason; you can special summon either your Red-Eyes Slash Dragon or Red-Eyes Black Dragon from your graveyard with them to either overrun your opponent or get more use out of your Slash Dragon.
Pro tip: to avoid your monsters being affected by Floodgate Trap Hole, use Red-Eyes spirit as chain link 2 or higher (for example chain it to the activation of your own Storm).
You can fusion summon Red-Eyes Slash Dragon with King of the Swamp and one warrior monster, however you cannot fusion summon Sky Galloping Gaia the Dragon Champion with King of the Swamp.
The reason there are multiple different fusion monsters included in the extra deck is because they could in certain situations be useful, and with the help of King of the Swamp they can be summoned. You lose nothing by including them since there is room for 5 fusion monsters in the extra deck.
Can help you cycle cards and fusion summon more often. Most of the time you’ll want to pick up a Red-Eyes Black Dragon during your end phase because you want warriors in your graveyard for the effect of Red-Eyes Slash Dragon.
It's because the chain link rule. If donpa SS dyna, donpa effect will be chain link 1 and dyna effect will be chain link 2. The donpa's destruction effect must be in the last chain link if you want to negate it.
Need to farm some packs and get a witch Raider or 2 to see how it would mix in.. imagine summoning witch Raider, wipe field, fusion into read using with,equip witch to read so if it dies you have witch back on field. Repeat if needed.
There is nothing quite as good, although king of the swamp can be a substitute for getting polymerization. Best to just use either a strong trap (mirror force, enemy controller, etc) or another warrior monster (exiled force) otherwise, then use restart to ensure a good starting hand
If "Time Wizard" on the field, toss a coin. if it's a head, destroy all your opponent monsters. if it's a tail, destroy all your opponent spell/trap , and your TW get 1000 Atk for each your opponent's cards destroyed.
literally every single card or page from any of the more popular decks will have someone complaining it's ''too OP''.If we follow that logic konami may as well ban every R and above card and let us fight with lvl 10 world duelists decks.
