This seems a lot like filler, until you've seen the rest of the series. It's setting a lot of stuff up in a way which isn't really obvious: Leomon, Jeri's obsession with "destiny", Makuramon being creepy/staring at Calumon and the earthquake for the next episode. At the same time, it works well as a standalone episode, giving the characters a chance to actually be quite funny.
This episode (apart from the whole "posters of girls in bikinis" debacle) starts off really strongly. Between the earthquakes, Makuramon and the reveal of Devas-as-Chinese-horoscope, there's quite a nice buildup of mystery here. Rika teaching Jeri how to play the card game is a really nice moment. Suzy's "I wish you weren't my brother" comment at the start certainly is the sort of thing siblings say, and I liked both how Terriermon called Henry on it and how it was recalled at the end of the episode. The place where this episode really starts to fall down is with the battle against the pig deva. The whole wishing for cards thing didn't make much sense either, but it mostly hit the emotional notes the episode needed, so I can kind-of forgive it for that.
There are a lot of really good bits in this episode, which the boring bits drag down. Makuramon's reveal/soliloquy works really well: the calm, steady voice he uses, combined with the implication that the Devas are fighting for their own survival, starts to lend a lot of the depth to the Devas which has been missing so far. Calumon's kidnapping and Leomon's return at the end is genuinely exciting, and it's nice to have a gender-balanced group of Tamers for the first time. I noticed that there's one frame of the shot of Hypnos on fire left in the dub. Finally, the last scene where the Tamers decide to go to the Digital World just really works to signal that everything is going to change.
This episode is both some welcome breathing room from the battle of the last two episodes and way to explore the Tamers' characters a bit further. The two-or-so seconds where Jeri walks through her bedroom before talking to Leomon is packed with information about her backstory: revealing both her younger brother (clutching the puppet) and the photo of her mother. Rika's scenes are pretty heartbreaking: she clearly loves her mum, and doesn't want to worry her, but doesn't feel that there's any chance she'd understand (asking her grandmother specifically to "Don't tell Mum, she won't understand."). Rika and Renamon's relationship, while not a romantic one (despite what one can read on the internet), works astoundingly well as a metaphor for one: this episode has both a "meeting the parents" and a "I must protect my beloved" hint about it there. I feel sorry for Henry, too… I figured that he tried to tell his dad that he was going a couple of times, but the easy opportunities slipped away and he was too embarrassed to really bring it up otherwise, so just sent the email.
Finally, I never noticed it before, but the Takato's flag is a total reference to the Seven Samurai flag.
