After the release of the Mini Box "Rampage of the Forest," Sylvan decks have have been dominating in PvP. This is because they are more accessible and easy to use since it starts with 1 Sylvan Komushroomo to destroy their opponent's monsters and spells and traps. But since Sylvan decks don't use a lot of spells and traps themselves because they need to excavate their plant monsters, this can be telling when they only set 1 monster on the field and pass the turn since it's most likely a Komushroomo, and negating it can be the key.
To know how to deal with a Sylvan deck, you'll need to understand their deck first, so be sure to check an example deck list first.
Since Sylvans decks are quite strong, there are a lot of people in the KC Cup that are using a Sylvan deck. It's good to prepare some counters against them if you want to climb through the ranks, as you'll most likely be facing plenty of them in both stage 1 and 2 of the KC Cup, while still being able to use them against other deck types of course.
You will need to pay attention if your opponent uses Rose Lover to special summon a monster. A monster that is special summoned using Rose Lover's effect is immune to traps for a turn, so make sure to not waste your Wall of Disruption, or Windstorm of Etaqua carelessly.
Keep track of how many Sylvan Marshalleaf and Komushroomo that are excavated and sent to the grave. If all 3 are already used, then you won't have to worry about getting your monster(s), or spells/traps destroyed.
Keep in mind that some Sylvan decks like to run cards that can return cards from the grave to the deck, and they will most likely return their Marshalleaf and Komushroomo.
If you think your opponent is playing a Sylvan deck, whether it's because they only set 1 monster, or because they used a Restart skill to show their hand, you can destroy their monster before they get to flip their Komushroomo.
Tribute to The Doomed, Parallel Twister, and Snipe Hunter can be used to destroy any monster, even if they are in face-down position.
The cost to use them is to discard a card, so it's better if you use these cards with certain cards/deck that can benefit from being in the grave.
Tribute to The Doomed can be good in a mirror matchup since you can discard a Rose Lover and special summon a monster, along with your normal summon to potentially win the game early.
Parallel Twister can be good in an Arkbrave Dragon deck because of cards like Paladin/Guardian of Felgrand, or good in a Paleozoic deck.
Snipe Hunter is arguably the most versatile of the 3 since you can target any card your opponent controls, provided they are not untargetable. This requires some luck and a cost of a discard though.
Assuming the worst, if a Komushroomo's effect activates and it sends a Marshalleaf and a Komushroomo, it will destroy both your monster and your spell/trap card. To avoid being left defenseless, you can use cards like Forbidden Dress to prevent getting destroyed, or banish it.
Forbidden Dress makes a monster untargetable, and can't be destroyed by card effects. But since it lowers a monster's attack by 600, it can easily be destroyed by battle, so it's best to use it on a monster with some good defense, or if you have some other protection cards.
Sea Stealth Attack is used in a Citadel Whale water deck, which is also a very strong deck that can go against Sylvans. When your opponent targets your monster, or the spell/trap card, you can activate Sea Stealth Attack to protect your monster and face-up spells and traps. But this will leave you open for attacks if you only have 1 monster and you banished it.
This method can be a tricky, and mostly benefits if you are also using monsters with flip effects like a Geargia deck. Since Komushroomo's effect states that it will only activate when it's flipped face-up, this means that if it's flipped face-up in a response to something, resulting in its activation being in chain link 2 or higher, it will miss its timing.
Since Geargia deck benefits from The Spell Absorbing Life anyway, this can provide a way for you to prevent Komushroomo from activating.
Geargiattacker also has a similar effect activation as Komushroomo, so you'll need to be careful when using it since you can also make it miss its timing.
Geargianchor will not miss its timing if you use Spell Absorbing Life in chain link 2 or higher, and it will let you destroy your opponent's monster still, but only if you have other Geargia monster(s).
Other useful cards
These cards aren't all that versatile, but if you are using certain decks that work with them, then these can be some optional ways to get rid of Komushroomo.
All types of deck are fair play IF AND ONLY IF we have 8000LP and 5 monster & spell cards zone !! Then every deck can be countered using brain. Sigh.... kids never play YGOPRO. Go check out the YGOPRO tournament gameplay, that's what I call quality. The lame matches in Duel Links are not even close.
I agree with you my friend. I personally play YGO Devpro. Anyone plays sylvan there. But in duel links all btainless kids play sylvan and now Fur hire. Fur hire is a new sylvan deck.... Konami is idiot...
I personally run a Sylvan Deck, and while I was climbing the D.D Tower, I got trashed. If you want to find a hard counter to sylvan decks, use a D.D deck. As sylvans' effects only active if their sent to the graveyard, that staple spell card of the D.D deck which causes cards to be banished instead actually stops the sent cards effects from activating. So using komushroomo will just and lock down up to 5 cards. No rose lover, no carrotweight... Sylvans are dying.
The spell fissure isn't released yet(or I overlooked it), so don't worry about your banned plants.
Sry for dissapointing the people who say that Sylvan in brainless deck. You guys must know that Sylvan is the only deck that needs brain and I will explain why.
So: All other decks are premade and you know all combos you have to use, so you dont use your brain. But in Sylvan, you must use only your brain to create your own combos. And the card that needs the most brain is Guardioak and Hermitree, coz you have to think carefully the order of the cards that you put on top of your deck...
"I beat sylvan cowards 9x out of 10 with my sea stealth deck.. sylvans are for cowards and people with limited intelligence." Because setting a trap card with whale takes so much intelligence you idiot. Sea stealth takes as much "intelligence" as Amazoness. Me play trap card and me hit attack. me smart
Sylvan is the best deck Konami ever created. You retard idiots sop crying about Sylvan power. You are just retards and can't win against us. I will play Sylvan forever and you will never defeat me. So go play Fortnite and stop crying, becauce you are noobs. Konami thank you for create sylvan, you helped me clear this game from antimeta idiots.
It not really garbage if u think about it is just Konami was just stupid in thinking a competitive deck would not be broken in a game where your deck is half of the normal size. literally just the core monsters need for this deck makes up the whole deck. not to mention komushroom, not broken in a normal 40 card deck, gives you over 25% chance of hitting the cards u would need in a 20 card deck.
And noww how to counter fuk..g slowbooks?? trap hole?
Can't wait until this archtype dies down kinda sad how most players won't accept how bs and clutch sylvans can be. Sure you can counter them with cards, but you're screwed over if you don't draw them first. Personally if Kumushroomo was limited to 1 it'd be fine.
remember back when Konamoney linmited Champions Vigilance because it was to strong with blue eyes kaibaman deck and also when it limited red-eyes revive?
yea.... sylvans surely aren't a problem.... lets not limit them....
KONAMONY GET YOUR SHIT TOGETHER!
