Wind Drake (strictly worse than Parasitic Strix), and Seacoast Drake or Training Condor (versus 1/1 lifelink Daggerdrome Imp), Snapping Drake 3/2 (versus 2/2 but with 2 lifelink direct damage in Bloodhunter Bat), and Azure Drake (worse except when no blue creature on battlefield, than Watchwing Scarecrow) were last to go out. Sentinels of Glen Elendra are equivalent to a second Nephalia Seakite. Parasitic Strix and 2X Tidehollow Strix then Swiftfoot Boots, Evil Twin, Sengir Vampire, Read the Bones and Scarscale Ritual, instead of 2nd Deathgaze Cockatrice, for more card draw, then 2nd Quag Sickness for indestructible akeout, were last to go in. Spined Thopter is probably next-most beneficial change. 3UU 3/3 Messenger Drake, vs 3U 2/2 Runewing are more potential card-draw.

Geist Snatch, Mental Vapors, Leonin Bola, Soul Seizer, Runner's Bane, and Wring Flesh (and the five Theros cards: 2X Nimbus Naiad, Coastline Chimera, Prescient Sphinx, Prognostic Sphinx) are not in yet.  Second Guess, 4X Pestermite, Invisible Stalker and Guard Gomazoa went into RogueMonoBlue. 2nd Serum Raker into RtR BattleDecks. Turn Aside and Psychic Barrier in LordUnrealDuffy.
