Legacy is a good tank, yeah. If you'd had out Danger Sense he'd've been able to ignore the dinos altogether (and the River of Lava, and the volcano, and the plants, and…) because it makes him immune to all environment damage (note that if an environment card causes him to hit himself, or someone else outside the environment to hit him, Danger Sense is of no use as it's not the environment actually doing the damage). He goes really well with Ra in Insula Primalis because of the sheer amount of extra damage Ra can get from that (potentially +7 damage - one from Galvanise, one from Inspiring Presence, a total of three from the Obsidian Fields if they call come out, and one from his own Staff and from Imbued Fire). Legacy is more about supporting the team but he does get to punch stuff occasionally (in which case the Nemesis bonus versus Blade can come in handy). Stuff like Take Down is good for a bit of control as well.
The Tempest card you're thinking of with all the draw would indeed be Localised Hurricane - causes Tempest to take +1 damage from everything (but you can cancel it out if you play his soak card, Otherworldly Resilience) but lets you nuke multiple targets and then draw some cards :).
Regarding your second game - Fanatic taking heaps of damage is normal for her. Check out one card in her deck, of which there is only a single copy - Wrathful Retribution. Often a game finisher, this is probably the biggest reason why you will want Fanatic to get beaten up as severely as possible :).
Sounds like you just had bad luck on Ab'Zero if you didn't manage to get his modules out until late - he has three copies of both of both of them and three or four copies of Onboard Modular Installation (which lets you search for a module as well as drawing and playing a card).
Anyway, got to dash off, have to go to work and I've left it a bit late posting this, oops lol.
It sounds like you're doing well! The more games you play, the more you'll start to notice the nuances of each hero.
For example, you said you didn't like how Fanatic seemed to just keep getting pumled with damage and needed some mitigation. What if I told you that Fanatic loves to take damage? If theres ANY hero I'd want soaking all the damage, its Fanatic! Wrathful Retribution and her Ageis are her biggest tools to use the damage she takes as a weapon. If you still don't like her candle burning that hot and fast, the Redeemer Promo Fanatic is the damage mitigating powerhouse you probably are looking for.
Glad to hear you're enjoying it! Keep playing and get ready for Citizen Dawn :)
Never worry about Fanatic taking too much damage--she's built to be that way. She wouldn't be a martyr otherwise! She's not what I would call a tank--she's just great at aggro.
It's more like whe doesn't fear death and attacks regardless the cost. I love Fanatic.
