Seismitoad EX and Aurorus are both new cards from the new set Furious Fists. Aurorus's ability Ice Shield can make Seismitoad EX a huge problem and almost impossible to deal with. A deck involving these two cards would be a 4-4 line with Aurorus, and 4 Seismitoads; Fossil Researcher would be a necessary in this deck to get Amaura on the bench. Seismitoad with a water energy attached to him and 4 Aurorus on the bench would give Seismitoad 260hp(counting the damage reduced, not actually that much hp). Another good card that would be in this deck would be Mountain Ring, so if and when you use Seismitoad's attack Grenade Hammer you will not do any damage to your benched Aurorus'. This deck could hold its own in a competitive setting due to its high damage capability.
