what deck did you guys hate when you first started yugioh? mine where
x-sabers
counter fairies
dark lords
any deck that used honest....

oh boy well i had loads..... but funnily enough when i started yugioh i ran a chainburn deck and exodia :c i hate them now but not back then XD
any way back to topic i hate darkworlds especially, dragunity, and lightsworn and basically any variation of a dragon deck be it blue eyes deck or chaos drags or dragunity i hated em all :c

lol i also hated any deck that used caius, i used to think that he was the most broken card XD

Exodia.... n it will never change...
also, i first hated gladiator beasts, sabers and infernties... although i start to like the former 2.. i still hate the later..

Hmm, I think that I would have to say exodia, and burn. Especially when I started out i was quite bad, so dealing with those decks were impossible for me.

and then once upon a time, u started using exodia D:

Hahaha. But it's piper exodia. XD And just to let you know, using the deck you hate the most gives you intel on how to better beat it.

X-sabers, Six Samurai, Chaos Dragon, Elemental Heros and Dark Worlds.
Those who had dueled against me know that I never used these decks.

Auto-pilot decks in general:

#1 E-Hero - most auto-pilot deck in the history of YGO.
#2 Malefics - a deck that only sacks can't have my respect.

I only hate getting sacked to be honest, being able to do nothing as your opponent got everything he needed to stop anything you do is like a painful, slow death.

As for decks, it has never changed, I only hate gravekeepers

used to hate list:
GB
GK
Burn

still hate list:
GB
GK
Burn

Used to and I still hate exodia, burn, mill, stall, instant win. Everything else is fine.
