Happy Field Friday! Fire King Island scores well as a Field Spell Card because it works very well in multiple decks. The effect that you can use multiple times triggers when it's sent from the Field Zone to the grave or banished. You have to destroy all monsters you control. That effect will trigger many effects in many decks that activate when monsters are destroyed. It also makes multiple copies of Fire King Island live. You could activate one and then activate another, which would send the first to the grave destroying all monsters you control. 

You have to chose one effect of the next two to activate and only once per turn. The first is to destroy one monster in your hand or on your side of the field. Then you have to search a Fire King monster from your deck to your hand. You can't activate it otherwise. Splashing a few Fire Kings into Kozmo decks hasn't been all that bad for them, and I'm sure it wouldn't be bad for other decks as well. Again, destroying monsters in your Main Phase and triggering their effects is great. The second of these two effects is to Special Summon a Fire Winged-Beast monster from your hand if you control no monsters. Basically that means if you have successfully activated the first effect, you can activate the second on your next turn. 

This common card is going to be splashed into at least a few decks simply because it can destroy your own monsters. Even if you don't run Fire Kings, run it if you run your own Field Spells to get rid of something like Kaijus or monsters stuck under Fiendish Chain or Fog Blade.
