Yu-Gi-Oh: 10 Most Powerful Unbanned Cards In The Game

Dark Ruler No More is the opposite to True King Of All Calamities but its a spell card that negates all face-up monster effects for the rest of the turn.

The real killer is your opponent can't respond to the activation of this card. This means they can't negate it or chain with a trap or monster effect. Granted no battle damage is done during the turn Dark Ruler No More is activated but you can still attack and destroy your opponent's monsters.

What cards like True King and Dark Ruler No More promote is zero interaction and little reward for playing your deck to its strengths. Player one goes through their deck and sets up a board full of monsters - this does take skill in memorizing your deck's combos with various cards - but all it takes is one card from your opponent to completely decimate their board and make everything they did a waste of time.

Cards that prohibit your opponent from responding to are very powerful and extremely unfair - imagine something similar in any other game, an item or gun your opponent just couldn't stop you from using but always resulted in a head-shot!
When your opponent's monsters have no effects it takes little to no skill in mopping the floor with your opponent's entire board and makes taking the win all the easier.
