Yea i meant this fusion monster lol. I'm trying to create a deck for when they do add this card. I know frontline base is a useful card and machina peacekeeper (to add a union monster to your hand.) But i wonder if fusion tag would really let you summon this card as i know some card effects won't work unless it's the o.g printed
Fusion tag doesn't work directly. You can technically change the name to VWXYZ-Dragon Catapult Cannon but this card also has a restriction that VWXYZ-Dragon Catapult Cannon has to be special summoned first.
But you can use fusion tag for the summoning of VWXYZ-Dragon Catapult Cannon.
