Alright, after looking over the rules forums, I've come to realize I have little idea how to correctly play a dark deck. Could someone either explain the rules behind playing dark friends and the like or provide me with a link to these rules? Thanks.

The rules for playing a Dark deck are notated on the Dark/Player cards.

Play Dark/Heartless as Friends, ignore 'Unique Card' rule. Cannot play regular Friends or Magic/Friends.

Cannot play Attack cards (Except D.Riku who can use Soul Eater)

For Dark/Heartless support value just halve their POW and round down.

Well what about the lvl rule? When can you play dark friends of higher levels?

In the same manner as playing normal Friends.

Oh nevermind, I guess I knew what to do after all. Thank you I wasn't entirely sure.

yeah and because you have to start by playing level 1 heartless friends it can take a little while to get to those really high ones.

are you absolutly 100% sure about that ?
