Dragon-Scarred Bear

Formidable was the keyword built to reward the wide green board without asking you to tap it, and this 3/2 is the clearest small-scale illustration of why that design works. The restriction (eight or more total power across your team) is a threshold a green aggro deck crosses naturally by its third or fourth creature, and once it does, the regeneration ability comes online. Regeneration on a body this cheap is normally an overpriced luxury; what changes here is not the activation cost (you still pay each time) but the gating. The ability stays dead until your board is already developed, which means you only get to hold mana up for it once you are in the kind of position where keeping a 3/2 alive actually matters. The condition is also the honesty: when you are behind and your power has been chipped below the threshold, the bear is just a fragile 3/2 with inert text, exactly when regeneration would be most valuable. So it is a snowball insurance policy rather than a comeback tool, good when you are already ahead and useless when you are losing, which is precisely the temperament green aggro wants from its early creatures. The lineage runs through every "rewards the board you already have" mechanic that pays out without demanding fresh creatures; formidable just made the check a one-time read of total power rather than creature count, so a single fat attacker counts as much as a swarm.
