Hello all.
I'm create deck for tryis etc, and I like game, so I want to built deck.
As I don't know much cards I'm use all my cards and create deck.

So, I wanna know what is chain? I have chain explosion and chain healing (I don't know is there on duelingnetwork that cards) but I want to know what is chain?

And how many cards you can have?

Also are there, and if yes are they work, cards like Change of Heart etc?

That's all for now.

And I'm find in my rl deck Galaxy-Eyes Photon Dragon...

How I can summon it...?

deck limit: 40 to 60 but its better to have like 40 to 42. change of heart is a banned card now but u can find other cards that are exactly like it with a different effect.

Ok, I know cards like it, it is just example... How to do that?

That effect.

today I'm play with someone who have change hearth...
And I'm find way.

I'll make a tutorial for you soon!
