The Fire King Sanctuary

Fire King Island Field Spell If this face-up card in the Field Zone is sent to the GY or banished: Destroy all monsters you control. You can only use 1 of the following effects of "Fire King Island" per turn, and only once that turn. ● During your Main Phase: You can destroy 1 monster in your hand or field, and if you do, add 1 "Fire King" monster from your Deck to your hand. ● If you control no monsters: You can Special Summon 1 FIRE Winged Beast monster from your hand.

If Ponix is our main Spell/Trap searcher, Island is our main monster searcher. It's hands down the card that makes all the magic happen.

You'll want to use its first bullet point effect every turn; during the first turn to search Sacred Fire King Garunix and get him on the field if you destroyed a FIRE monster, and later on to search any Fire King you need.

The second effect comes up much less often. Even if you have a FIRE Winged Beast in your hand, you're better off destroying it with the first effect and search something.

Not even Sacred is worth using for it. In fact, you'll often destroy a copy of Sacred in your hand just to grab another copy from deck - getting his Special Summon effect to go off is just that crucial to the deck.

Running 1 copy is mandatory, 2 copies is recommended.

Beware its first effect - if this card goes to the GY or is banished face-up, it takes all your monsters with it. As such, Fire King Sanctuary is essential to ensure you have a way to protect Island.

Sometimes you can use this effect to your advantage, by playing another Island on top of it, or destroying it with High Kirin. However such cases are rare, most of the time you want Island to stay in the Field Zone.
