Everyone seems to get a guaranteed 6* card for completing the Tutorial. I've got mixed feelings about that. On one hand, they're not really "Mega Rare" cards if EVERYONE is guaranteed to get one. On the other hand, I'm sure they can't reach their maximum potential without having a second copy and the proper Evolution Materials, so THOSE are the ones that will end up being truly rare.

I ended up getting the Holy Priestess (6* Light Card), which compared to some of the other ones I've seen, seems a bit more useful in all situations.
Active Skill: Heal III (Recovers HP equal to 10x of member's recovery power. 20 Turn Activation Period.)
A useful ability to have if you're having unlucky spins against a boss, but largely unnecessary early on because of her ...
Leader Skill: Healing Light (Recovers huge amount of HP each turn.)
And when they say huge, they aren't kidding. It's currently healing about 200% of my maximum HP, every step, without needing to rely on the slots.

Most of the other 6* cards I've seen have element specific skills - boost the attack/health of one particular element of cards, nullify attacks from one particular element, do extreme damage to an opposing element (but nothing else), or improve the chances of a specific element appearing on the reel for several turns.
All of these are useful to have in specific locations, but the Holy Priestess is a reliable to have ANYWHERE, so I'm glad I drew it.
