Feelings Entrusted from my Father - S1.E150

Temporal Machine God Sandaion's attack points are then lowered from 4,000 to 0, by the effects of Infinite Machine Ein Soph. When Z-ONE attacks Yusei's Ancient Fairy Dragon with Temporal Machine God Michion, Yusei's life points are reduced to 750, by Michion's ability. As a result of the damage, Yusei's duel runner plunges down again, but Yusei is able to navigate through the structure of the Ark Cradle, and find his way back to Z-ONE. But when Z-ONE attacks with Hanion, and then Raphion, Yusei is able to protect himself from taking damage, and losing to their effects, by timing the activation of Scrap-Iron Scarecrow, and his Synchro Believer's ability.
