The effects of the other "Lightsworn" monsters will aid in the Summoning of "Wulf, Lightsworn Beast".
Since this card cannot be Normal Summoned, it's effectively useless in your hand. Use "Magical Mallet" or "Reload" to return it to the Deck and to draw some cards. Other cards that discard cards can also be used to get rid of this such as "Lightning Vortex" or "Raigeki Break". "Solar Recharge" can also be useful for removing this card from your hand, then it can be brought back with "Glorious Illusion".
While "Plaguespreader Zombie" is in your Graveyard, and "Wulf" is in your hand, "Wulf" can be placed on the top of your Deck to Summon "Plaguespreader Zombie", and Synchro Summon something. Then, at the end of your turn, when a "Lightsworn" will be milled, "Wulf" will be milled, and that will give yourself a powerful Synchro Monster along with a "Wulf".
"Charge of the Light Brigade" can also be activated instead of waiting until the End Phase. This "Wulf" will also be used as a Synchro Material, along with "Plaguespreader Zombie". Since both were Special Summoned, the monster added to your hand by the effect of "Light Brigade" can be Normal Summoned. If "Lumina, Lightsworn Summoner" is picked, her effect can be used to Special Summon "Lyla, Lightsworn Sorceress", then use her effect and Synchro summon for "Mist Wurm" or any other level 5, 6, 9 or 10 Synchro Monster (of course any other "Lightsworn" monster instead of "Lyla" will do.
This is a good card to discard with the effect of "Lumina, Lightsworn Summoner".
Since it can be Special Summoned from the hand by an effect, use "Photon Lead" to make this card more useful in the hand.
