Okay lets get this out the way...I didn't get this for the coupons. Coupons are good (never seen a bad coupon. So the coupons in this pdf get a thumbs, because they are coupons and saving money is always good.
Now onto the feats, since there six I will break it down feat by feat.
Animal Defender 4/5
A very good feat, prerequisites low (only one). It helps add value to ranger or druid's animal companion. Useful when combine with aid another for attack bonus. Unfortunaly it can't be used with flanking.
Bardic Scream 4/5
A good feat, of course its for bards. This feat is very good if you run out of spells and party has already received your buffs. Now your party won't mind that you scream like a girl at the sign of danger. Since it's sonic damage it if very good for breaking objects as well as ears.
Blood Casting 2/5
A good idea, this need to made into a prestige class not a single feat. A lot of dice for very little in benefit. "But it can increase the DC of my spells"...Well so can spell penetration and the greater version of that and it's not random. This is good feat if you like to roll dice or are a wild mage.
Critical Smite 3.5/5
A good feat, now you can put the smack down on the netural baddies in the world.
Use with a sap to knock out the villian neutral guards with out losing you powers.
Raging Shout 3.5/5
A good feat for helping your allies (who doesn't want temporary hit points and will save bonuses). You can't rage if you use this ability, but you also don't get tired after using this ability.
Spontaneous Luck 5/5
What, now there is a use for those level-0 spell slots beyond 5th level. "Oh crap I rolled a 1 on my reflex save...*poff*...no I didn't." Personally I think this is way too good to give clerics this. It should have been made with a number of times per day.
