What are the best Synchro Monsters in Yugioh?

Crystal Wing Synchro Dragon

It’s pretty good and reasonably generic, but what really pushes it over the edge is the 1 card Windwitch - Ice Bell combo that him out with using your normal summon, only 2 cards in your extra deck and make him immune to destruction by your opponent's card effects.

Yeah, good luck getting him off the field at that point

Shooting Quasar Dragon

This guy can win a game on it’s own. It can attack twice with it’s beefy 4000ATK body so with an open field he can swing for game by himself.

Then he can negate any effect and when he dies you can summon Shooting Star Dragon which is a pain in the ass to deal with as well

He’s basically an OTK machine

Beelze of the Diabolic Dragons

An out to so many cards and decks. He comes in and out of formats depending on how effective he is against the dominant deck.

He can be destroyed and gains attack every time you take damage so he can become massive, he’s just so bloody hard to kill.

Honorable mentions

Black Rose Dragon - When in doubt, Go Nuclear!

Denglong, First of the Yang Zing - Why, why is he generic, just why?

Trishula, Dragon of the Ice Barrier - When “I got Trished” is a popular term in Yugioh, you know you have something
