Equip this card with "Armor Breaker", because each time "Spell Striker" attacks, 1 card will be destroyed on the field.
This card works excellently as Tribute fodder, especially for "Monarch" monsters. "Pot of Avarice" can help cycle the reuse of both "Spell Striker" and the "Monarchs".
Equip this with "Mist Body" and "Mage Power" to make it virtually indestructible and power it up at the same time.
This card is generally good in Speed Synchro Decks.
When destroyed by an effect or in battle and equipped with a Spell Card, the Equip Spell Card will usually end up in the Graveyard, enabling another "Spell Striker" to be Special Summoned from your hand for a Tribute or possible Synchro Summon.
This card is especially good in "Crystal Beast" variants, as it is easy to get Spell Cards into the Graveyard. It can be used as either Tribute fodder ("Kuraz the Light Monarch") or for a Synchro Summon.
