- This card can be searched by "Single Purchase", "Sangan", "Witch of the Black Forest", "Resonator Engine", "Vampire Dragon" and "Dragunity Corsesca".
- This card's summon can easily be set up by first Link Summoning "Mistar Boy", whose effect also raises this card's ATK to 1900. You can then use this card and "Mistar Boy" to go into a Link 3 monster.
- You can also Synchro Summon a Level 4 Synchro Monster using only WATER material, banish both material to summon this card and overlay this card with the Synchro Monster for a Rank 4 Xyz Monster that enables "Black and White Wave".
- This card's effect is best utilized with cards that can Special Summon monsters to the other side of the field:
- "Ojama Trio" can summon three tokens, denying your opponent their next three Draw Phases.
- "Black Garden" can summon a token each time you summon a monster. It is advised to play "Black Garden" after you have summoned "Fenrir" and before you have used up your Normal Summon. This way, "Fenrir" will be strong enough to destroy the token spawned upon each of your Normal Summons, thus allowing each one of your Normal Summons to skip your opponent's next Draw Phase.
- If this card would be destroyed, "Salvage" can return it to the hand. "Nimble Sunfish", "Swap Frog", "Skreech" and "Mother Grizzly" can ensure this card's summoning conditions can still be met.
- The similar effect of "Yata-Garasu" can be applied when your opponent controls no monsters.
