as time passes, YuGiOh has evolved from very basic monster fighting kind of duel to very complex gameplays that involves one-turn-kill or first-turn-kill.

As such, that very first turn becomes so important that more often than not, the first player has the upper hand and most of the time proceed to win the match.

finish your opponent within 1 turn or even the first turn seals the match quickly, its saves time, it saves the trouble. hence recently we saw many decks that resolves around OTK and FTK merge. that very first turn becomes so important that every player wishes to turn the game to their advantage, so that even if the combo fails, it leaves the opponent with nasty situations that he cant deal with.

that is why we saw the infinite hand-dropping xx-saber loop, infinite DDB-bombing xx-saber loop, magical explosion OTK, trishula remove everything loop/combo.

they have one thing in common, maximise that one turn you have, and finish off your opponent.

since trishula is from Duel Terminal, we wouldnt have a chance to see it in action in the coming world championship.

and right now, there is one deck that is still capable of executing that: xx-sabers.
