First, Normal Summon "Protector with Eyes of Blue" to Special Summon a level 1 LIGHT Tuner monster from your hand.

Then, send "Protector with Eyes of Blue" to the Graveyard with its own effect to Special Summon "Blue-Eyes White Dragon." Now you're ready to Synchro Summon "Azure-Eyes Silver Dragon"!

You can bring back the "Blue-Eyes White Dragon" you used as a Synchro Material at the beginning of your next turn with the effect of "Azure-Eyes Silver Dragon"!
