Mind Crush vs. Debunk

Mind Crush

Declare 1 card name; if that card is in your opponent's hand, they must discard all copies of it, otherwise you discard 1 random card.

- It's harder to master compared to Debunk and easy to read & played around, it can hit (it doesn't let things hit the field) multiple cards (Multiple decks) and it doesn't matter if it's Spell, Trap or Monster but the best thing is getting information on their next play(s).
- The effect of Dropping a "KEY" card out of their hand is really strong, regardless of the fact that he/she may use it later for a comeback so it's almost like one for one but not always! Because using mind crush vs. decks that depend on "Discard Traps" like Phoenix Wing Wind Blast in Prophecy can backfire, since they just discard the card you called and you have to discard.
- One more thing i need to address about this card is that: the card isn't strong when you're losing so it won't help you there same thing when you're winning, all it can do is to prevent your opponent  from making a comeback.

Debunk

Negate the activation of an Effect Monster's effect that activates in the hand or Graveyard, and remove it from play.

- This is one of the best  and most powerful counter traps available to any deck right now. It used to handle decks like "Dark World" but it's very meta relavent right now with effects in the hand and grave appearing in the game. Almost every top deck I can think of has multiple effects which activate in the hand or graveyard.

- This card is very live now at the start of this format because unlike the last one, (well, Soul Drain still Limited) & also Hand Traps may run the meta, at least we're sure about that for now in this order: (Effect Veiler - Maxx "C" - Swift Scarecrow - D.D. Crow - Battle Fader)

- Now when it comes to Fire Kings, the fact that we have probably 2/3 room left in the side cuz all the current meta need to be shut down by cards like: Skill Drain, DNA Surgery and Imperial Iron Wall plus 2/3 copies of SIM/LIM (bad match ups vs Dark World with Dragged down, Dark Smog & Mind Crush / Bujins with Kaiser Colosseum).

- Debunk is better than Mind Crush when it comes to those decks:

Archfiend - Battlin' Boxers - Bujins - Chronomaly - Dark World - Dragon Rulers - Fire Kings - Ghostricks - Gusto - Hazy Flame - Heraldics - Mermails - Frognarchs - Psychics - Zombies.
