yugioh takes tons of skill! like predicting which cards (that would otherwise be completely useless) you need to hide up your bum. yes, that is how the "heart of the cards," works.
I don't play much anymore. I usually run burn decks, the boros legion of ravnica achieve this in a very cheap way for me. I started with a rainbow/ sunburst deck though.
I also made a deck that revolved around this card. (no, its not real)
