I can run 4 Heavy Storms?

Today I'm taking a look at a card that could see play in sideboards. Malevolent Catastrophe is a trap card that destroys all spell and trap cards on the field but can only be activated when your opponent attacks. Sounds powerful right? It's almost like the powerful and broken Heavy Storm. This card is mostly used against aggro decks that run Royal Oppression or against anti-meta decks who main board tons of spells/traps to protect their Doomcaliber Knights and Thunder King Rai-Oh. This card is fairly useful against Blackwings as it can destroy multiple copies of Black Whirlwind, Royal Oppression, or Icarus Attack. Its also very strong against Gladiator Beasts hitting their key Trap cards in the battle phase like War Chariot. This is a great sideboard choice for Lightsworn, although I think Cold Wave is a better choice, or My Body as a Shield. If the game ever slows down look for Malevolent Catastrophe to make a splash in a lot of control oriented decks.
