Its not all going the birds as the endangered species here is a white rhino. The deck is based around blinking ETB effects, with a slow grind intended when the rhino hits the table.
Overall strategy is to use the exile and counter spells to drag the game out long enough to find and cast
Stonehorn Dignitary
. Play your other creatures and blink for their ETB effects as needed. This includes: 1) huge amounts of scry, 2) a bit of life gain, 3) some offense, 4) some defense, and 6) some enchantment hate. You have numerous blink cards to play with, but make sure you save at least one for the rhino (the flashback on Momentary Blink will be useful here).
Sideboard strategy:
BorosKitty: -3 Mana Leak, -2 Journey to Nowhere, -2 Crookclaw, +2 Aven Cloudchaser, +2 Disenchant, +3 Serrated Arrows (if they have 1-mana creatures, and dont forget you can blink the Arrows)
Affinity: -3 Mana Leak, -2 Crookclaw, +2 Cloudchaser, +2 Disenchant, +1 Battle Screech
Delver: -3 Mana Leak, -2 Crookclaw, +1 Serrated Arrows, +2 Cloudchaser and +2 Disenchant (if Spire Golems or other artifacts, otherwise no change)
MUC: -2 Mana Leak, +2 Dispel (to counter counters)
