Craniamon - The Ultimate Blocker Shield

Last night I encountered a player that played a Craniamon deck that triggered me to write this engine, his deck totally destroyed my black Cresgarurumon strategy, but weak over the green bee sting deck.  The [BT3-075] Craniamon is a super rare rarity card that introduced in BT3 Union Impact, his main effect is "In both player's turn: All of your digimon with Blocker cannot be destroyed by your opponent card effects". This effect causes Gaia Force or Trump Sword or [BT1-023] Skullgreymon become useless againts any blocker on the field. The only way to kill Craniamon is to attack him with a digimon that has more than 12K DP when the Craniamon is resting.
