Remember that Equip Cards are also destroyed whenever the monster they are equipped to leaves the field. If a "Vylon" monster equipped with "Vylon" Equip Cards leaves the field due to a card effect, this card's effect will let you Special Summon one "Vylon" Tuner for each of those Equip Cards.
Note that the destruction of any Equip Cards must be the last thing to happen on the field in order to use this card's effect. This card will miss the timing if the Equip Cards are destroyed because the monster they were equipped to was used in a Synchro Summon, because that Summon would've been the last thing to occur.
Equip a "Rod of Silence - Kay'est" to a "Vylon" monster while this card is on the field, then equip that same monster with a "Vylon" Equip Spell Card. "Rod of Silence - Kay'est" will destroy that spell and activate this card's effect, and the spell will activate in the Graveyard to add another "Vylon" Spell from your deck to your hand. You can continue doing this to fill your field with "Vylon" Tuner Monsters until either your deck uses up all of its "Vylon" Equip Cards or you run out of space for summoning on your field.
Set up this combo by using "Vylon Cube" for a Synchro Summon. It's effect will let you add "Rod of Silence - Kay'est" straight to your hand. If "Vylon Cube" had a "Vylon" Equip Spell equipped to it, you can get this card from the deck at the same time.
Search into "Vylon Matter" to recycle "Vylon" Equip Spell cards from your Graveyard to continue using this card's effect. "Pot of Avarice" could do the same for the Tuner Monsters once they've been sent to the Graveyard.
Keep in mind that this card only disallows the Summoned Tuners to be used for Synchro Summoning a non-"Vylon" Synchro Monster, but you can still use them for Tribute Summon, or even Xyz Summon
If you control "Vylon Tetra" and another monster, you can ram it into your opponent's monster, equip it, then ram that monster again to Special Summon a Tuner from your Deck.
"Collected Power" can focus all "Vylon" Equips on the field onto one monster. This can summon a bunch of monsters at once if a "Vylon" monster was about to be destroyed. The same can happen if the chosen monster was a non-"Vylon" monster, because those cards will be immediately destroyed since they can only be equipped to "Vylon" monsters.
You can combo this card with "Vylon Vanguard" for both field and hand recovery.
While this card is face-up, use "Creature Swap" to give your opponent a "Vylon" monster equipped with as many "Vylon" Equip Spell Cards as possible. Destroy that equipped Monster with a card effect to get this card's effect and search out new Spells at the same time.
