1 "Dragunity" Tuner + 1+ non-Tuner monsters
You can banish 1 "Dragunity" monster from your GY, then target 1 monster your opponent controls; banish it. If this Synchro Summoned monster in its owner's control is destroyed by an opponent's card: You can Special Summon 1 "Dragunity" Synchro Monster with 3000 or less ATK from your Extra Deck. (This is treated as a Synchro Summon.) You can only use this effect of “Dragunity Knight - Ascalon” once per turn.
