The thirteenth card is the Sacred Phoenix of Nephthys, a sacred being who dies and comes back to life shortly after. Basically a Jesus analogue. This cards resurrection effect comes into play when it’s destroyed by a card effect, and destroys all spell and trap cards on the field, if it’s beaten in battle or banished it doesn’t get to come back. While it does have the resurrection ability it also only has 2400 attack, which is pretty low for an 8 star monster. There is a Nephthys archetype this is included in, which has multiple ways of summoning this from the deck or hand, either by actually summoning it, or destroying it in the deck so that its ability activates. While its attack isn’t great, using it with it’s archetype you can get it to the field pretty easily, and it’ll bounce back from any traps that would have cleared your field.
