That's not correct! You can only use 2 semi-limited CARDS per deck, so:
1) Use 2 Dakini and 0 Machine Angel Ritual;
2) Use 1 Dakini and 1 Machine Angel Ritual;
3) Use 0 Dakini and 2 Machine Angel Ritual;

You´re wrong bro! This is different from TCG rules.. so in this case you can just use 2 of the semi-limited cards on your deck! Read carefully and you will understand better ^^
