rolling [CHAOS] will still cause these abilities to trigger
This set also introduces Big Hero 6 and Chip 'n Dale: Rescue Rangers
In general, I would look at these two factors when looking to include cards not of your tribe's creature type: Is this creature so strong that it, on its own, is generally stronger than my tribal creatures when they are receiving bonuses and/or empowering my other cards
Since Team Rocket arent a large part of the franchise anymore, frequently being replaced by other teams like Aqua, Magma, Galactic (and the list goes on), theyve aged since weve last saw them, and thereby, their rarity is going up, too
The set is top-shelf, and each color (which includes multicolored and artifact/land) is spot-on
Still, the Battle side is the kind of thing that helps you win a longer game
