This has got to be one of the worst skills in the game. You don't even get a choice between Ritual Monster or Spell. Just take 200 more, and you can use Yugi's Destiny Draw to get ANY card, so this skill is trash.
I am not a big fan of ritual summons but Dakini is Limited 2, as is the specific spell for summoning it. Dakini has the ability to return a ritual monster or spell to hand, I think. Is it not worth building round this?
