Obstinate Evolution (Standard)

This is an agro flyer deck which focuses on mostly low costs creatures (1-3) to gain early entrance to the board. Expectation is to be continually attacking. Overtime, creatures will gain power and number until other side is forced to concede.

The undying creatures have a few layers to play:
1 - constant "wall" defense for flyers
2 - continually attacking to help trigger Beastmaster Ascention and Military intelligence
3 - upon removal from board, they are a constantly revolving door to trigger evolve
4 - upon entrance to battlefield from graveyard, +1/+1 provides synergy with Renegade Krasis for added +1/+1's

Renegade Krasis is used less as a creature and more for its +1/+1 ability that affects the other creatures on the board. This means self-bouncing with Quickling and Peel from Reality to reset its original P/T amounts to trigger additional +1/+1 counters.

(Note that both Esperzoa, and more importantly, Howlgeist is perfect for this)

Gyre Sage is used to open up more creatures for the board and giving earlier entrance for Howlgiest, Behemoth, (Note that Niblis of Breath has mana synergy). Gyre Sage also gives more usages per turn for blinking mercurial pretender and Elder of Laurels boosts.

Paragon of Gathering Mists has one important use - allow Renegade Krasis's ability to work with all blue creatures. It also has great synergy with master of waves.

The cultivator of the deck goes to Mercurial Pretender as it goes wherever it can to assist: as a blinking Krasis to take advantage of reoccurring Howlgeist for more "+1/+1, adding a layer of +1/+1 as Paragon of gathering mists, blinking obstinate beast for more life, another mana pool as gyre sage, as blinking Craterhoof Behemoth for insane +1/+1's, and finally ability to make unlimited amount of elemental tokens from Master of Waves as it can blink out and original Master of Waves takes over "control" of those tokens.

As you can see, goal is to get out fast and continue to grow strong fast.

This is just a theory-build as this is the first time building a deck for me, so advice is much appreciated.
