The Fire King Sanctuary

Relinquished Anima Link 1 DARK Spellcaster 1 Level 1 monster, except a Token You can target 1 face-up monster this card points to; equip that face-up monster to this card (max. 1). You can only use this effect of "Relinquished Anima" once per turn. This card gains ATK equal to that equipped monster's. ATK 0

Anima enables us to perform the [Sunlight Wolf recycling pattern] more easily, in case we had to Special Summon Legendary Fire King Ponix instead of Normal Summoning it. (Remember, Salamangreat Almiraj requires a Normal Summoned monster as its Link Material.)

And besides that, he's just a good staple to have around. His monster-equipping effect can come in handy against opponents who don't manage their zones correctly.

We heavily recommend running 1 copy if you own it.
