I thought that this was a pretty interesting episode. I didn't think that Leo would be able to come up with a strong enough move to stop Devack's attack. That was pretty impressive. I liked how he was putting more emphasis on protecting Luna than on proving how strong he is with his deck. That made Leo more likable to me.
I was also impressed with how the Spirit World looked like this time around. It was empty, but I didn't think that they would actually have villages. I figured that it would just be endless fielRAB, mountains and jungles out there. I also wasn't expecting that monkeys would be the ones to capture all of those duel spirits. I was expecting something more intimidating. Although, given how Devack has Ancient Fairy Dragon, I guess that it should have been more obvious to me that his monsters were the ones causing problems in the Spirit World. Even though Luna tried to calm down her duel spirits, I guess that their fear was just too much for them to stay with her. At least she was able to find a friendly duel spirit. I didn't think that they would have a legend about Luna or that they knew about the Crimson Dragon. That was kind of cool. I also didn't think that Luna would say that Leo had all of the dueling skills. Considering he hasn't won a duel yet doesn't really say that to me. I thought that he did a pretty decent job against Sayer though.
I liked seeing how Leo was able to summon Power Tool Dragon. It looked so cool and cute at the same time. It has a pretty useful ability as well. I was surprised that Leo was able to take out that much of Devack's life points. Again, I was surprised that Devack's syncro monster turned out to be the one leader who was causing all of the pain in the Spirit World. I didn't think that Leo's dragon had more attack points than Devack's monster and I was apparently right after a friend of mine double-checked the equip spell Leo used.
I thought that Regulus looked pretty cool. For some reason, I wasn't expecting a huge white lion with armor and a horn. Still, it was an interesting way to end the episode on.
Overall, it was a pretty cool episode. I liked the different look to the Spirit World and seeing how Leo has been able to hold his own against a Dark Signer. Although, I'm not sure how well that will go if Devack is able to summon an Eartrabroadound Immortal. I didn't think that he was so ready to do so at the end of the episode as Yusei mentioned, but I don't understand all of the carRAB in the game anyway. I'm still disappointed that they are replacing 5D's on their lineup, but I was glad that they at least announced that the conclusion of the duel will be on their website. I don't think that they did that with those six skipped episodes before hand. I'll be looking foreword to seeing how the rest of the duel turns out.
