Ever since their release, synchro monsters have made the game much more fun and enjoyable. It gave Konami more freedom when it comes to designing new cards, synchro monsters can be insanely powerful with the trade-off of difficult summoning conditions. Over the years, stronger and stronger synchro monsters have been released, yet the veteran cards are still going strong. Finding the right monsters for your extra deck can be a pain, understandably, as there’s countless synchro monsters to choose from. Hopefully this list will help you to determine which cards are best for your deck!
10. Formula Synchron
Quite a few high-level synchro monsters require a synchro type tuner monster as their summoning materials. Formula Synchron was born for this, acting as a link between your little monsters and those big boss cards. Additionally, you can use it to synchro summon in your opponent’s turn and also draw a card when it’s summoned!
9. Crimson Blader
What an awesome level 8 synchro monster, Crimson Blader is a game-winner in the right situations. It needs some protection as it has no innate spell/trap security but if you can destroy a monster, your opponent’s turn will become ten times more difficult. Getting rid of a card like this requires a higher ATK monster if Crimson Blader is protected. Summoning the needed monster is almost impossible though if this card gets its effect off!
8. Ally of Justice Catastor
One of my personal favorites, I’m a big fan of Neo-Spacian Grand Mole so I was amazed when I saw this card. Ally of Justice Catastor can take down any non-dark attribute monster it likes with its effect, destroying them before damage calculation. For a level 5 monster with 2200 ATK, this effect is actually quite insane.
7. Brionac, Dragon of the Ice Barrier
Simple but effective, Brionac can guarantee an OTK if needed. While its ATK & DEF stats are quite low, the competence of Brionac’s effect cannot be understated. It’ll give you the opportunity to clear your opponent’s field before you finally go in for that killing blow. Such an effect is also great for returning any of your cards or dumping cards from your hand into the graveyard!
6. Clear Wing Synchro Dragon
The only level 7 synchro monster you will ever need is this one, it offers way too much to turn down any other. Let’s be honest, pretty much every deck has easily accessible high level monsters. Clear Wing Synchro Dragon is the bane of such cards, shutting them down before they even get going.
5. Goyo Guardian
Goyo Guardian has arguably the most restrictive synchro materials on the list (as it requires an earth attribute monster) which knocks it down a few rankings but my god, it had to make the top 5 at least. No wonder it was banned for years, such a disgusting effect was broken before it hit the forbidden list. A level 6 monster with 2800 ATK & the ability to special summon any monsters it destroys is ludicrous!
4. Stardust Dragon
One of the more classic cards on the list, Stardust Dragon was among the first synchro monsters for us to be introduced to. Even though it was released nearly 10 years ago (seriously!), you shouldn’t underestimate this card as it can save your day if used in the right situations. Having the ability to negate a destructive card is surprisingly underutilized but Stardust Dragon is both easy to summon and powerful when it hits the field.
