I had that exact card when I was a kid, and yeah, Mammothmon has been my favorite ever since.
I also like Vikaralamon, and now I'm having him in my team in HM.
Though I have a shit ton of favorite Digimon, I really love them all except for Agumon Bond and one or two that honestly don't look that good to me. (I don't even remember, it's not even worth going thru them)

>I wonder if we will get a underworld like biome for all the undead and nightmare soldier Digimon.
Gods, I hope. I think they've shown a tiny bit of the fire domain, but it's been mostly just water and forest domain.
