have royal magical libray in def mode and have gerfred the iron knight in atk mode
equip butterfly dagger elma to him and give up 3 counters from magic libary to draw a card eventuly you will draw all peices of exodia

Not meaning to be rude, but.....

You're WAY behind if you just figured out this combo...either that or you're very new since ANYONE who's played the game for a while knows the Gearfried + Elma combos

Gearfried + Elma + Library = lots of draws

Gearfried + Elma + Magical Marionette = lots of destruction + ATK

Gearfried + Elma + Morale Boost/Magic Absorption + Fire Princess = burn


And, for another note, you won't be able to use that combo anymore in Advanced Format since Elma is going to be banned as of April 1st.
