1 Tuner + 1 or more non-Tuner monsters If this card is Synchro Summoned: Target 1 face-up card you control and 1 face-up card your opponent controls; return those targets to the hand, but for the rest of this turn, you cannot activate cards, or the effects of cards, with the same name as those returned to the hand by this effect. You can only use this effect of "Vulcan the Divine" once per turn.
Returning your cards back to hand lets you reuse them.
Relatively low base stats.
Returning your own card back to hand is not always viable.
Cannot immediately reuse card that was returned to hand.
Return your monster that was debuffed or attached with a negative effect back to the hand.
While not being a Fire Fist monster by name Vulcan the Divine works very well with them. They have the same attribute and type so Vulcan can share their support. Vulcan can return the Fire Formation backrow to clear space and allow you to reuse them while also returning an opponent’s card to their hand. Finally, Brotherhood of the Fire Fist - Spirit can be used as material to summon Vulcan.
