A deck focused on controlling your opponent and burning their life points quite easily.
A good starting hand is:
2x secret blast, 2x just desserts, 1x demise of the land.
If you play first set all of your hand, pass. Then wait your opponent to have enough cards on the field, and wait for special summon. When they special summon you activate demise and activate the mystic mine. Then chain activate secret blasts and just desserts.
For me in one round I nearly wiped out all 8.000 life points just in one turn.
Then they are locked because they can't activate any effects because of the mine.
