You can use Massivemorph on your opponent’s monster to disable it from direct attacking, and then equip that monster with Axe of Fools to make your opponent take 500 Life Points damage every one of their standby phase.
The Unfriendly Amazon would benefit the most from using Axe of Fools because it will negate this monster’s effect of requiring a Tribute of your own monster during each of your standby Phases, and greatly increases its own ATK to a whooping 3000 ATK. Similarly, you can Normal Summon Mist Archfiend and equip it with Axe of Fools, therefore Mist Archfiend will not be destroyed during the End Phase and you do not take 1000 damage. Using Axe of Fools on Gandora the Dragon of Destruction will negate its effect of being destroyed during the turn it was Normal Summoned, but it will also rob its effect of banishing cards from the Field to increase its ATK. Using Axe of Fools on Cloudian - Eye of the Typhoon will further increases its ATK to 4000, while allowing it to be switched to DEF position without being destroyed, but at the same time it loses its immunity in Battle and can be destroyed by your opponent’s monsters.
Why? I'll tell you why, it's because if you go back and take a screenshot of the thread it's going to look very similar to mine. Conversations on this thread should be strictly yugioh or duel links related and nothing else, it's as simple as that.
Another mask of the accursed... this card will improve burn decks since in the current meta spell and trap effects are much more important than the atk of the monsters. Even this card will increase the atk of a monster my enemy controls, there are so many ways to protect myself by monster attack for example draining shield, mind eye temple, massivemorph etc... this card also negates the effect of an opponent's monster, another reason to use this card on opponent's monsters and not on my owns
This card has way too much potential to be a dead draw or backfire in such a deck. You'd be better off with Burning Land if anything. (I wouldn't be shocked if Goblin Thief was better in such decks, actually.)
