Pretty simple to play, get your creatures out fast,then get your pumps out.
Gladecover Scout is here as a nice hexproof one drop, that can be pumped up rather quickly. (I've had a 16/16 Trample, Lifelink, first strike Gladecover Scout turn 4 before.
Hero of Leina Tower is a nice one drop that can be pumped massively, thanks to the many 1cmc spells in the deck.
Akroan Skyguard turn 2 flyer that can be pumped quickly.
Ethereal Armor 1cmc pump that just gets bigger and bigger
Reap What Is Sown, Give 3 creatures each a permanent +2/+2 for 3cmc. yes please.
Ranger's Guile Protect your creatures, and get a little pump.
Gods Willing Protect your creatures, get a little pump or sneak through for the kill.
The stars of the deck
Unflinching Courage Amazing by itself, but also is amazing with Ethereal Armor and our next star Eidolon of Countless Battles
Eidolon of Countless Battles A turn 3 Eidolon of Countless Battles thanks to Hero of Iroas is nice, a late game Eidolon of Countless Battles is also very amazing. Oh well I bestow Eidolon of Countless Battles, and swing for 20, flying, trample and lifelink.
