[STRATEGY] 4-CARD DRAW CARD COMBO
You can easily draw 4 cards by combing "Card of Sacrifice" with the upcoming card "Blackboost". "Blackboost" lets you draw 2 cards by removing 2 "Blackwing" Tuners from play. If you have 2 "Blackwing" Tuners with low ATK, just activate "Card of Sacrifice" to draw 2 cards, then use "Blackboost" to draw another 2! Since these are both Trap Cards, you can even do this combo on your opponent's turn!
