Use this card to trigger "Appropriate", or while "Appropriate" is already face-up, you can turn this into a +2 for nothing.
Combine this card with "Silent Magician LV4" to provide another way to speed up adding Spell Counters to this card to increase its attack and lead into Special Summoning for "Silent Magician LV8".
This card works well in "Chain Strike" decks. Activate "One Day of Peace" and chain your burn cards to this this card. Your burn effects will go through as they are higher in the chain link and your opponent will be unable to harm you during his/her turn.
If you use this in a beat-down deck, you can attack with many monsters, inflict a lot of damage, then activate this card during Main Phase 2 so you don't need to worry about your opponent's comeback.
This also works in helping avoid the negative effect of "Power Bond" being used to Summon high ATK monsters such as "Ultimate Ancient Gear Golem" or "Chimeratech Overdragon" (its ? ATK becomes its original ATK, in other ways the damage that "Power Bond" inflicts). If the duel is not won the turn "Power Bond" is activated, activate this card to avoid a potential massive loss of Life Points.
