This should play like it looks, white aggro. Very fun deck and won't cost a lot of money to build. Have fun and enjoy and as always, tips and comments are welcome!
Playing the deck in a nutshell: Hero of Iroas is a big part of the deck. He makes it so that bestowing the other creatures is much easier and faster. I often can have him a over a 10/10 by turn 4 and sometimes bigger. Another big part of the deck is the lifelink, do not underestimate Hopeful Eidolon! I will cast him turn 1, especially if I have an Ethereal Armor in hand and NOT a Hero of Iroas. Otherwise I bestow him and just start reigning in life. Last week I was at 87 life by turn 8.
So ya, bestow your guys on the heroic guys to make them big. Enjoy your life gain. Below is a description of each card in the deck and why its there. I would very much appreciate playtest, comments, and +1's if you like it!
Hopeful Eidolon is the other 1 drop. Nothing fancy at first, just a 1/1 lifelink ... but add an Ethereal Armor on to him and now he's a turn 2 3/3 (or a 7/7 lifelink if you put 2 of them on him ... on turn 2!). He's also a great bestow for Fabled Hero and now with Hero of Iroas you can bestow much faster
Hero of Iroas - talk about versatile! A great 2/2 2 drop with heroic +1/+1 counters the real value he adds to the deck is reducing the cost of Aura spells by 1 colorless. This applies to bestow costs as well making the bestow creatures much easier to cast earlier on.
Akroan Skyguard - another 2 drop for early damage, this 1/1 flyer also plays on the heroic counters to grow strong later on.
Fabled Hero is a beast. Throw a Gift of Orzhova and Ethereal Armor on him and watch as things get out of control in a hurry. Use Gods Willing to protect him from removal and set off his heroic.
Eidolon of Countless Battles - Grows with the board state. A great bestow for anyone in the deck and latter on stronger on his own as well.
Heliod, God of the Sun is there to provide Vigilance and chuck out enchantment creatures (which work wonders for Ethereal Armor. That and the fact that he will usually be a creature by the time you play him and things are looking up.
Ethereal Armor can play very early and on the right creatures can cause havoc and win games.
Gods Willing will help protect from removal and also a way to get past defenders. Great way to boost up the heroic and get a scry in as well.
Ajani's Presence meant to save creatures against Supreme Verdict and other such removal. Also helps boost heroic if I have the mana available for more heroic targets.
Selesnya Charm - Who doesn't love options! Whether it's giving Fabled Hero trample with his double-strike or exiling a Desecration Demon I am never unhappy to have this card!
Banishing Light - deal swith planeswalkers or anything else that you need to get rid of while at the same time boosting Ethereal Armor
Gift of Orzhova give a boost of flying and lifelink, how could I resist, and only costs 2 once you have Hero of Iroas out
Ajani, Caller of the Pride - great card early on to start pumping up counters and then when I have threat, send them in with flying and double-strike.
Ajani, Mentor of Heroes - .... Do I really need to defend this boss card? Ajani, I love you. So very, very much!
SIDEBOARD:
Fiendslayer Paladin loves to fight against those R and B decks. The lifelink and first strike also helps buy time against other Aggro decks.
Deicide - great removal at instant speed, especially with all the enchantment creatures in this block.
Reprisal - some cheap instant speed removal to target those big baddies like Desecration Demon, Polukranos, World Eater, Master of the Feast, etch
Glare of Heresy good ole fashioned white removal. Great against stuff like: Detention Sphere, Elspeth, Sun's Champion, Boros Reckoner, etc.
Revoke Existence - good removal for all the enchantment and artifact stuff out there.
Brave the Elements built in for the same purpose as Gods Willing but in a mass setting. Either an all out attack with everyone or as a mass damage protection.
Pithing Needle - pretty much a sideboard staple
Gift of Immortality fits the aura theme of the deck and good against removal black decks. Also helps against Desecration Demon when you can sac your same creature every turn and have them come right back.
