It's so broken it's bizarre. Dimensional Prison targets. This is banishing without targeting, which is the ultimate 🔥 effect, AND stealing a monster without targeting. This card is not a specific support card for Gagagigos so it's widespread 🔥 that can be put in any deck.
It sees basically zero play. Unless every single Duel Links player is an idiot (which I can't rule out), this would point to it not being as broken as you think it is. It's too slow, and the damage is a big deal.
That's why ppl use it now in memory of the duelist cuz yes it can be thrown into any deck and counter almost any card imagine turn 10 your on a B.E deck and you just manage to make a max dragon n win. Except your opponent threw it down n now you lost cuz he's got your max FOR FREE WITH NO REPACUTIONS this card needs working on atleast
