This thread os about any kind of trading card and the combos you can make with them. I only collect Yu-Gi-Oh cards, but this is for ANY kind of card.
One of my favorite combos to use is to play Bad Reaction to Simochi (healing your opponent is now hurting them) and then playing The Eye of Truth (see your opponent's hand, if there is a spell card in there, heal your opponent 1000 points during their standby phase). This way, you can see your opponents hand, and possibly destroy your opponent in 8 turns if they have spell cards in the hand. My strategy (interestingly inflicting direct damage) half-revolves around BRtS, and so I have a Mask of Darkness (FLIP: take back a trap card from the graveyard) in my deck, too.
