Brimaz, King of OreskosRegarding the manabase:I hate including gates in a deck like this but I feel it's necessary mainly because of Brimaz and Agent; I generally want to cast these cards ASAP if I draw them. I have also chosen to include more Swamps than Plains because my one-drop creatures are all black and I need a Swamp to cast them on T1. My deck has more white spells than black ones, but I can operate on a single white source in the early turns.
Regarding Creatures:Tormented Hero has two power for one mana with Heroic upside.
Cruel Sadist requires only one activation to become a Bear (but can grow bigger if you need her to). You will probably never use her second ability, but hey, it's there in a pinch.
Lone Missionary is a Piker that triggers Pridemate, helps pay for Ulcerate, triggers Mentor, and helps you win damage races. Fine card here.
Child of Night is a Piker with basically the same benefits as the Missionary, except she has to get into combat to realize them. Still a fine card here.
Ajani's Pridemate is a Bear with a ton of value in this deck because of all the ways to gain life. I'd consider this a core card.
Hero of Iroas is a Bear that's amazing in any Heroic deck because he just wins games on his own if left unanswered.
Vizkopa Guildmage is the best remaining Bear that's on-color because it at least gives you the option to sink some mana into it; I wouldn't ever want more than one of these and it's not easy to cast on T2, so one copy is fine.
Mentor of the Meek turns all your Bears into cantrips. Enough said.
Agent of the Fates is a solid creature at the top-end of an aggressive deck, and with all the ways to trigger him he is a big part of the deck's removal package. Attacking with him and casting Swift Justice pre-blocks forces one sacrifice and the resulting first-strike plus deathtouch creature he becomes usually eats a second creature (if they have one).
Brimaz is Brimaz.
Regarding Spells:Gods Willing protects your guys, triggers Heroic, and has the sweet delicious gravy of Scry on top.
Swift Justice is amazing in a combat-oriented deck because it triggers Heroic, triggers your Pridemates, and acts as removal in a lot of cases.
Ulcerate is an amazing removal spell in any deck that can afford the life payment and this one can.
Nimbus Wings provides evasion to push through damage, triggers Heroic, and brings your dudes outside the range of a lot of the common removal. We also have the synergy with Hero of Iroas, but that's just more delicious gravy.
