I'm fairly certain that this season is the third season of the series, there being 20 eps in each of the first two seasons.
I particularly liked the way it was shown how the Danians are able to transform a creature into one of their own. It reveals how the Danian Queen's sentence on the Mipedian spy (from the episode "Big Time" from last season, one of my faves) was carried out. Nice continuity. Definately one of my favorite series based on a card game, along with Magi-Nation. Actually, except for the different color palette, the new animation kind of reminds me of Magi-Nation's.
