[Discussion] Was there a card that once printed changed the game completely?

Soul charge is a less talked about one, but it let a lot of very niche and random archetypes see competitive play, sylvans, infernity (seriously hated infernity) and to a lesser extent, lightsworn because of that card. Oh and synchrons were a pain in the ass with their very easy quasar/double quasars on turn 1)

101/castel; yeah this basically made people scared to summon big heavy boss monsters and changed the game to spam dem rank 4s remove their stuff and otk, I still get salty whenever I have to deal with this card/castel

Artifact Moraltach + artifact sanctum, yeah noone runs backrow hate because these 2 cards would punish you for it.

Sixth Sense; call 5 and 6 draw 6 because your lucky af otk opponent, mill 4 otk them anyway dumb fucking card, either slightly worse foolish or you break the game and draw a billion cards.

Cyber dragon, RIP goat format where gravekeeper's spy was good because it had 2k body and summoned a 2k body. Very little is BAD about the card in its time, infact it was probably the best card in the game.

Towers; this card is unaffected by blablabla all started here, I honestly started laughing like a maniac when I saw this card, yes towers wasnt so bad but it gives us fucking cancerous cards like great magnus or ultimate falcon. Most big bosses have some ridiculous protection in comparsion (see kozmo dank destroyer, eclipser and dark planet). Also people ran king crab in everything just to have a random out to this stupid card. Fun fact, in it's 1st itteration before printing, your opp chose what you sent to grave and you could not avtivate the effects of the sent card.

Kaijus, RIP big boss monsters, its a 2200 turtle now

DAD, introducing the 200$ a piece card which singlehandedly ruined the game for many many people brought with it a tier 0 format and basically made teledad unbeatable
