* Traps and Spells, generally, are used to gain the upper hand on an opponent. Since this card prevents either from being used for a while, your own included, it's best to use this card only when you already have dominance over the field, to keep your opponent from springing a surprise on you.
* Combo this card with Spells/Traps that rely on being sent to the Graveyard/banished("[[Shrub Serpent]]", "[[Z-ONE]]", etc.), since they do not activate.
** This also means that "Cold Wave" can be splashed into an "[[Artifact]]" Deck.
* If you combine this card with a card effect that will negate your opponent's monster effects, you can maintain total control of the field for a turn. Useful cards could include "[[Destiny Hero - Plasma]]", "[[Dark Ruler Ha Des]]" or "[[The End of Anubis]]" (the latter two are most useful if the opponent's monster cards activate in the Graveyard).
