Target 1 face-up Monster Card on the field; banish it, and if you do, Special Summon it to its owner's field during the Standby Phase of the next turn. You can banish this card from your GY, then target 1 "Centurion" Synchro Monster in your GY; Special Summon it, but it loses 1500 ATK. You can only use 1 "Centurion Phalanx" effect per turn, and only once that turn.
