Delta Accel Synchro (デルタ・アクセル・シンクロ) is a form of Synchro Summoning, in which one Synchro Tuner Monster and at least two or more non-Tuner Synchro Monsters are required, as with the Summoning of "Tech Genus Halberd Cannon". It was used by Antinomy, when performing Top Clear Mind in episode 144. It has also been shown that performing Top Clear Mind sucessfully for this summon can turn a nearby star or sun into a black hole that lasts for the remainder of the current duel.
