King's Synchro

[Trap Card]

When your opponent's monster declares an attack on a Synchro Monster you control: Negate the attack, then you can apply the rest of this card's effect. Banish that Synchro Monster you control and 1 Tuner from your GY, and if you do, Special Summon from your Extra Deck 1 Synchro Monster whose Level equals the total Levels the banished monsters had. (This is treated as a Synchro Summon.)
