[STRATEGY] SYNCHRO MATERIALS STRIKE AGAIN If you Synchro Summon using monsters like "Tuningware", you can use "De-Synchro" to Special Summon them and use their effects again. Use it on a Synchro Monster that you used "Tuningware" as a Material Monster for to Special Summon "Tuningware" and then Synchro Summon again. You'll get to draw another card! You can also Summon a different Synchro Monster to take advantage of the new situation.
