Prioritize Null Gravity Barrier Monsters
The main hazard is Gravity Barriers. The Drones will shoot Gravity Barriers on the first turn of every stage. Use NGB monsters to move around the map
Can Avoid NGB Monsters
You can bring Drone Breaker monsters to deal with the GB generating Drones. You can also bring monsters with high damaging Bump Combos like Susano'o to completely ignore them.
