DISCLAIMER: THIS LIST IS BASED SOLELY ON PERSONAL OPINION.
I'm just gonna come right out and say it: Equip Spells are garbage.
Sans a few broken ones on the Banlist, "Moon Mirror Shield" making any monster automatically stronger than its opponent, and "United We Stand" and "Mage Power" being neat in Goat Format; Equip Spells, in general, are suboptimal at best. The vast majority of them offer a finite stat boost with no significant protection or other worthwhile enhancement. Even the ones that do are more often than not exclusive to barely useful monster...
Ever wanted to cheat?So easy,there are a lot ways.
1.Prepare deck,and on turns you have just a strong cards like Dark Magician,Blue Eyes White Dragon (i have it not deck of it) and many more!
2.Use a strongest card in one turn.
3.Never ever say that you listened to this article cause,people will look at it and cheat against you be careful.
4.Last turn,you have to choose a strongest card EVER to beat your opponent easy.
5.Drop all weak and useless cards.
Look at those cards,they are so easy to cheat with.

Yami: So, Tea had a beautiful short red dress and looked amazing!
Yami: So, I told her…
Yami: That she is beautiful.
Kaiba: Yami: look!
[Then they saw where we are shown a tall building]
Yami: Wow, what is this?
Joey: Good morning! The Wheeler Towers is now opened for business.
Kaiba: More like Dorkland Towers to me.
