* In order to use this monster's ATK-reduction effect, it is necessary to take effect damage on the same turn. This can be easily achieved through the effects of "[[D/D/D Abyss King Gilgamesh]]", "[[D/D/D Oblivion King Abyss Ragnarok]]", "[[Dark Contract]]" cards, or effects like "[[Ring of Destruction]]", "[[Destruction Ring]]", or "[[Tremendous Fire]]" (the former two, as Trap cards, will also let you use the effect during your opponent's turn).

* You can easily Fusion Summon "[[D/D/D Dragonbane King Beowulf]]" Send this card to the GY (by Tributing this card or using it as material for a [[Fusion Summon|Fusion Material to send it to the Graveyard]] or [[Link Summon]]). Then, use this card's effect to send "[[D/D Necro Slime]]" or "[[D/D Vice Typhon]]" from your Deck to your Graveyard. Banish both this card and "Necro Slime" with the effect of "Necro Slime" to set up their Fusion Summon "Beowulf"effects.
