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

Many KoG deck use this card at 1, I personally use this at 1. Sometime you need an out for a big monster that otherwise you don't. Sometime this can steal game by helping you attack "directly".

If your deck has space left to add something, add something far more useful than a fucking Riryoku. A tech like Wild Tornado, a single tribute monster (like Knight of the Red Lotus in Harpies), or literally anything else. The guy that said he reached KoG with Riryoku hasn't even demonstrated it!

This card was great but after kc cup it became crap. Great for farming. No good PvP pmdeck will have it. To many common counters and doesn't stay on your character.

It should be rated like grave keeper vassal. 10/10 for farming and 3/10 for PvP.

still overrated lol
Do you know that "Riryoku" means "Force/Strength" in Japanese?

Well, guess what this card is called in Japan? It is just called "Force"(フォース). Oh, and Riryoku Field is just called Force Field in Japan. Somehow the translator thinks that calling this card "Riryoku" is more straight-forward than calling it "Force".
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

Same. Got my last orb from Pegasus, now I can't get this in the trader.
Worth having a 2nd one?
How the hell is this not banned in pvp

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.
