This card can be very powerful by using its effect to send the top three cards to the Graveyard, which could turn out to be cards like "Wulf, Lightsworn Beast", "Treeborn Frog", "Destiny HERO - Malicious", "Volcanic Shell", who all work very well in the Graveyard or any monster that could be brought back.
This card works great in a Zombie Deck. Almost any good Zombie-Type card can be placed in the Graveyard and either revive it (with "Il Blud", "Zombie Master" etc.), or use its effect (like "Mezuki").
This card can help meet the Summoning conditions of "Woodland Archer".
Being a LIGHTBeast-Type monster, this can work well with "Ojama" and/or "Raccoon" monsters, particularly if the Deck contains only Beast-Type monsters, as it won't affect "Solidarity".
This card can combo with "Gladiator Beast" monsters. It makes a good bluff when your opponent thinks that "Gladiator Beast Hoplomus" is face-down. Also, its milling effect can be useful for when "Gladiator Beast Equeste" is used to bring them back to your hand.
However, since most "Gladiator Beast" Decks only run few monsters, this card will most likely mill Spell/Trap Cards rather than Monster Cards, so be careful.
This card can be Special Summoned by "Debris Dragon". "Debris" can be Normal Summoned to bring this card back, and if there is a "Doppelwarrior" in your hand, "Doppelwarrior" can be Special Summoned and together they can Synchro Summon a "Scrap Dragon".
Ironically, this card sees more play OUTSIDE of the "Lightsworn" Deck. They usually only use 1 or 2 as it is deemed too "slow". However in Decks such as Plants and "Flamvell", it sees play in three, as it fuels your Graveyard with "Dandylion" and "Spore" and provides fuel for "Rekindling".
If any "Gusto" monster is milled this way, they can be shuffled back into your Deck later with "Caam, Serenity of Gusto" or other "Gusto" support cards.
It also works nicely with "Junk Synchron", whose commonly found in most pure-ish "Gusto" Decks.
