Yu-Gi-Oh! The Duelists of the Roses

you can't get riryoku for yourself unless you use a cheat device, but be careful as it might mess up your ps2, it did mine when i tried it....but then i stupidly overwrote the file because i wasn't thinking and i had to start a new game from scratch....there are only 808 total cards you can get, 45 of them are unobtainable unless you use a cheat device. Blue Eyes can be obtained through slot jackpots

For Blue Eyes, you can check the FAQ for Jackpot slot line-up. If Seto uses it, then it is possible to obtain it in the Slots.

And for Riryoku, you CAN obtain it without a cheat device. You have to fight the Fab Llyr that uses the card, and obtain it in slots. (I think it's the one that adds to a monster's ATK by half of your current LP)

Hope that helped.

Dude...obviously you havent played this game, or else you would know that most good cards, including blue eyes and riryoku, dont show up in the slots, because they want you to be challenged to win (even though if you know how to play, its no challenge at all)

For Blue Eyes, I managed to obtain it by lining up 3 "Panther Warrior" after I defeated Richard Slysheen of York. Give it a try.

Line up 3 Dancing Elves to get one.

and since people are interested in listing the cards they lined up to get a blue eyes, i got my first one by lining up Uraby after defeating rex

Get 3 in a row. completely random. it doesnt matter what cars they are. but i did get 2 of mine from deck leader card from that "duel". but it is random.

I know you can get it from lining up many diffrent cards so try lining up and you will be getting it once you get good at lining

Actually nps_pon2182 is right blue eyes and riryoku, dont show up in the slots

i got my First Blue eyes today by lining up Three seven completed

one of my old save files i could get rare cards in slots, but my new file i can't... this is just an idea, but maybe a deck leader hidden ability allows rare cards to appear in slots, or possibly a name , i do recall seeing rare cards though and i dont use cheats,

right now my deck leader is
-wings of wicked flame-
type- pyro
attr- fire
atk- 700
def- 600
summoning level - 2
rank- 3stripes 1 star BG
dc- 13

leader abilities
--------------------
extended support
increased strength for same type
weaken specific enemy type - ? not sure
spellbind specific enemy type - beast
destroy specific enemy type - plant

and also 2 hidden leader abilities
top , middle , and bottom arrows in slots
destiny draw

im sure other cards have hidden abilities as well , possibly rare cards in slots
or i might just have to much faith in this game :P

also, i think i got blue eyes from 3 megamorph
