A spell's total cost includes either its mana cost (printed in the upper right corner) or its alternative cost (such as flashback), as well as any additional costs (such as kicker)
Grand Arbiter Augustin IV (SL Fallout foil $5) People kill this blatherer on sight, because its annoying, but when a card is good, it gets targeted
It has two hoses you must place inside of it (it can get a bit tricky when sliding the reservoir in and out of the machine), one for the overpressure valve bypass, and one to draw water to the pump
It provides protection against anything your opponent throws at your monsters, barring battle destruction (which you can deal with using the Field Spell and/or Genesis)

Ironically, this last card is probably my favorite in the deck, despite the fact that it does one of my least favorite things
