Rating9.5 /10

Riryoku is a very powerful card and ranks highly in terms of card efficiency due to its ability to both decrease your opponent’s monster ATK and add it to your own. Unlike equip cards, Riryoku could only be negated by spell jammer or counter traps which could negate spell effects. Could be included in most decks that otherwise do not use effect damage to win.


  • Very useful to defeat any high level attack monster.
  • Damage dealt is similar to direct damage, since it is the base attack of the attacking monster.
  • Very flexible card.


Only useful for 1 turn.


This cards effect only lasts for a turn, so use it wisely. It's usually best to use it on targets that have higher ATK than anything you have on the board or in your hand.

Riryoku works well in any beatdown deck and is necessary to decks to get high score with Over 5,000 (9,999) Damage duel assessment.

Not sure why this card is rated as a 9.5. You should only ever run this card in farming decks to increase Cerberus's attack, and never in PVP. Cards like Metalmorph or even other continuous spells such as Gravity Axe are more useful since they are permanent buffs and can't be negated as easily as Riryoku. Nearly every deck has Windstorm of Etaqua, and 1 or more copies of both Enemy Controller and Sphere Kuriboh, which basically just makes Riryoku a wasted card

Calling it a "great" "counter" to Mirror Wall is a huge stretch. It's a one time use card to bypass Mirror Wall against 1 monster for 1 turn and can easily be negated by the likes of Windstorm, Econ, and Kuriboh, all of which are in near every deck. The opponent having one of the aforementioned cards set is way more likely than the opponent having a Mirror Wall set.

It validates plenty of decks in PvP, fuck off with this nonsense.

How is it nonsense? Literally the only PVP deck that uses Riryoku are Victory Viper decks, which aren't exactly common or very good. Its only use is for farming, and even then Gift of the Martyr is better

Dude , ur argument fails miserably .In terms of battle ,wich is the most important thing in pvp ,riryouko is the most powerful spell card in the game since u can defeat ANY monster with any monster of ur own ,and yes it is a great counter to mirror wall and RE ,but when it comes to windstorm kuriboh and Econ ,Don't those work in any situation in pvp ? Don't they work against relinqueshed,GK,HHG ?

Why Im not able to target a fusion monster like meteor b dragon with Riryoku? It doesn't make sense...

Same for me. No obvious effects in play that should have prevented this. No way he's not classed as a 'monster' card...

Is this card still available? I've been checking for the last week in my trader and haven't seen it.

Not sure, I've been checking the past week too. It was there like 2 weeks ago, but I needed an extra ultra rare orb so I waited instead of converting something

do some missions, maybe also convert some UR cards you don't need and wait for it at the Trader. That's what i did
Is it worth to have a 3rd copy of this card? Like for farming purposes?
auto deul decides not to use riryoku. the one right now i am face two twin headed dragon. i used golden apple and so i got a monster with 2800 attack. i have riryoku in my had. im waiting for autoduel to activate riryoku. but instead it ends my turn. i let that one slide. on my next auto duel didnt use riryoku. i turn off auto duel and manually activate riryoku to win the game. riryoku has glitched on me many times before and i have lost multiple times. most of the time that i auto duel im at work so all i see if i won or loss. so i probablly way more than i am aware of. has anyone exerienced this?

Yeah, auto battle stupidly uses Riryoku and also Stray Lambs and Tornado in my battles too... Always uses Stray Lambs for no reason, Just summons lambs and ends turn. Newer uses Tornado on strong cards in its situtation for example if Jurassic World and Raise Temprature was both face up on field, always uses on Raise Temperature. Always uses Riryoku on my cards for no reason.

There aeems to be a glitch beetween Ancient dragon and Riryoku. I had in play one twin headed thunder dragon and lord of d and my opponent had one ancient dragon at turn 3. I played riryoku and the game didn't let me target AD to half atk. On turn 4. My opponet played a Riryoku too. He wasn't allowed to target ancient dragon for half atk or add atk...

Lord of D effect. While he is on the field you can't target dragon type
Is it worth going for a second Riryoku?
