GWU - Bird Tribal - Derevi's Destiny (Casual) [Revision 2]

Really simple and brutal deck, made from my daughter's "bird" tribal request.

Quickly pump out a flying army of Birds (that get bigger if killed or if left alone), lots of draw, proliferation for counters on Door/Aerie/Cloudfin. Enlightened tutor is a great tuning card to find you a missing mana when you need it (artifact lands) or to go grab Akroma's Memorial for a strong win support. Can also situationally grab you missing combo enchantments like Coastal Piracy or Descendant's Path for deployment acceleration, or Sigil of the New Dawn if you're dealing with a lot of creature removal.

Plays extremely consistently, and brutally effective. Not many decks can handle a flock of massive flyers swinging constantly.

Notes on creature selection and Sideboard options:
PRIMARY:
Birds of Paradise: Must-have mana fixer and accelerator, also a useful attacker later.
Thrummingbird: Must-have proliferate to pump the whole army (or even just a Cloudfin) quickly.
Cloudfin Raptor: Not a must-have, but it provides color-balance and syngergizes with Thrummingbird who is a must-include.
Healer's Hawk: The lifegain gets out of control quickly and gives you extra time to outpace and overrun most opponents.
Squadron Hawk: Searching for the additional 3 birds is a quick way to pump-up Doors and build a fast army of birds, helps against removal.
Derevi: The token tri-color legendary to lead the attack. Also helps keep the army Vigilant before Akroma's hits the table.
ALTERNATES:
Mimeomancer: Adds a quick power boost to the smaller birds that stacks with Door/Aerie.
Mindcensor: Great counter for tutor/search heavy decks.
Cloudchaser Kestrel: Enchantment removal on a body.
Commander Eesha: Alternate army lead for Derevi if you're up against a heavy protection/reach defense.

Notes on support selection and Sideboard options:
PRIMARY:
Coastal Piracy: Easy card draw with lots of flying creatures.
Descendants' Path: Freeplaying creatures that still triggers Door of Destinies
Door of Destinies: Core army power/toughness booster.
Soulcatchers' Aerie: Core army p/t boost that punishes opponents for creature removal.
Sigil of the New Dawn: Helps retain creatures against heavy removal.
Enlightened Tutor: Key hand/mana/combo fixer that can also go grab Akroma's Memorial.
Akroma's Memorial: If you haven't won the game yet with all the other card combinations, this one ensures you will.
SIDEBOARD:
Flurry of Wings: Huge army boost, especially late-game. Good replacement for Sigil if you aren't against much creature removal.
Additional Enchantments: Balance options to focus your combo needs (Piracy, Path, Sigil).

Please leave feedback if you like the deck.

Note: This is a casual theme deck that still plays very competitively in my local game shop, so any changes/additions must fit the "Bird" theme.
