Alrighty let’s get down to it, this tip is for fast level 8 synchro summons. This tip will help u to bring out Stardust Dragon faster and Red Dragon Archfiend even Hot Red Dragon Archfiend but sadly not for Beelze of the Diabolic Dragons.
Alright, summon out Summoner Monk and by effect switch him to defense position. Then by his second effect discard a spell card to special summon from your deck a level 4 monster. From your deck special summon Top Runner. Top Runner is a level 4 tuner monster. Send the two to the graveyard to synchro summon any level 8 synchro monster. Now if you want to change things up a bit, play the normal spell card Falling Current and target either Summoner Monk or Top Runner and declare a level between 1-3. The monster becomes the designated level. If you chose 3 u can send Top Runner and Summoner Monk to the graveyard to synchro summon Black Rose Dragon or Ancient Fairy Dragon or any level 7 synchro monster. If u declare level 2 with falling current you can synchro summon Celestiel Wolf Lord, Blue Sirius or any level 6 monster. So u get the idea that this setup for synchro summons is fast.
Now you can always play the spell card Double Summon to conduct 2 normal summons to synchro fast as well, which is actually faster, but I would consider including the above stratagem if you want to have more than one type of opportunity to synchro summon.
I hope this was useful. Thanks for reading!
