Normally this card requires a cost of 1000 Life Points to activate, but the effect of "Destiny Hero - Diamond Dude" only activates the effects of Spell Cards, so costs and other requirements are not necessary. So using "Diffusion Wave-Motion" with Diamond Dude's effect will allow you to attack all monsters on your opponents side of the field for free. You would still need to target a Level 7 Spellcaster to apply the effect on.

Use "Diffusion Wave-Motion" with any powerful Spellcaster-Type monsters like "Dark Magician", "Dark Magician of Chaos", "Sorcerer of Dark Magic", etc.

This card becomes really deadly combined with "Final Attack Orders" and "Ojama Trio".

If all but two of your Spell and Trap card zones are filled and you have a Field Spell in play, equip the attacking monster with "Mage Power", then activate "Diffusion Wave-Motion" for filling the last two spaces and deal an extra 3000 points of damage. This strategy can be even more devastating when used with the above one.

A really devastating combo is if you are facing a field full of weaker Attack Position monsters and you have a "Dark Magician" and a set "Secrets of the Gallant", along with this card in your hand. Activate "Secrets of the Gallant", and then activate "Diffusion Wave-Motion". Each attack forces your opponent to discard 2 random cards, and if you can inflict battle damage to enough monsters then you can probably leave him/her with no cards in his/her hand.

You can use this card in combination with "Neos Wiseman" to clear your opponents Monster Cards without fear of "Neos Wiseman" being destroyed by face down Spell Cards or Trap Cards. This will also inflict a lot of effect damage and recover you some Life Points due to "Neos Wiseman's" effect. Combine this strategy with the above one for a huge amount of damage.

Use "DNA Surgery" on "Mirage Knight", and activate "Final Attack Orders", to deal 2800 damage for each monster destroyed. You could also use "Jinzo" equipped with "Amplifier" to keep "DNA Surgery" from being negated.
