Except that it's a 0 ATK, 0 DEF monster if you don't have a trap, so against say Dragon Spirit of White decks this card would just be a sitting duck that. And considering it's a ritual monster, it's way too slow to even keep up with decks like Dragon Spirit and Masked Heroes. It's a good card to counter Amazons though
you don't actually needs level 8 monster since it is a DARK attribute ritual monster, you can use "Ritual Raven" monster for entire tribute same thing goes with Zorc.
It's about as good as a Level 8 Ritual Monster in Duel Links should be. Maybe even SLIGHTLY weaker than it could be (though still not bad). Also, let's be real, even after this thing gets released, Cyber Angel Dakini will still be by far the strongest Level 8 Ritual Monster in Duel Links anyway.
With Djinn in SR as a new drop I suspect komoney are trying to force Senju and Sonic back into meta so all the recent players have a whole buncha old boxes to whale on
