Woah, this is harder than I thought. There's definitely a difference between one's top 10 favorites and an objectively "best" or even "good/powerful" top 10. With that in mind, and in no particular order. . .
Mirrorweave - I guess I'll turn my swarm of tokens into
Grave Titans. Seems fun. Almost as fun as last game when I turned all my opponent's attacking dragons into 1/1 Myr before blocks. This card can do so many obscene things offensively or defensive, and at instant speed. What a house.
Monastery Mentor - I like noncreature spells, and I like tokens, ergo... Oh, and the prowess is just unbelievable gravy.
Frantic Search - If durdling was a single spell, it might be this one. Mostly I like the way it synergizes with so much of the other stuff I like to play, like
Underworld Breach,
Rielle, the Everwise,
The Locust God,
Shabraz, the Skyshark/
Brallin, Skyshark Rider, etc.
Sevinne's Reclamation - I've played a LOT of non-green decks over the last couple of years. This spell has pulled so much weight in the non-green value/ramp/recursion department. I still think it's criminally underrated.
Ponder - There's very few situations I wouldn't want to resolve a
Ponder. Card selection, shuffle effect, top-deck manipulation, spell cast trigger, cheaper than dirt. Delicious.
Mirror Entity - I love a good token deck, and this thing makes them hit hard. The real appeal is the wacky stuff you can do with creature types though. Activating for
x=5 or so while you have a
Deep Forest Hermit and
Captain of the Watch in play is just good, clean fun.
Jeskai Ascendancy - It's a lightning rod for removal, it combos too easy, it floods the stack with triggers that can sometimes take a bit to resolve, and I don't care because I love it anyhow. One of my favorite plays always and forever will be convoking an
Hour of Reckoning with a board full of tokens and this card in play.
Worm Harvest - Repeatable token production on a very large scale in the right deck. Right up my alley. This plus
loam, cycling lands, and lots of self-mill and aristocrat effects is just delightful to play out.
Ramunap Excavator - Maybe my favorite source of value in the game. Simple. Clean. Wonderfully effective. Playing a fetch/
Fabled Passage/
Krosan Verge over and over just feels like cheat mode. Not to mention the
Strip Mine locks. If I owned
Crucible of Worlds I suppose that would be preferred, but I don't so nyah.
Pitiless Plunderer - Probably my favorite aristocrats piece. I first learned to love him in an old
Ghave, Guru of Spores list, and I still play him today in cube and in a
Sidisi, Brood Tyrant deck. It's no wonder I love him, because he's basically a forerunner to
Kykar, Wind's Fury in the way he plays with saccing tokens for mana.
My honorable mentions would go to
Felidar Retreat,
Akroma's Will, and
Mystic Reflection, which are new enough that I can't really dub them all-timers yet, but they are certainly making me feel some kind of way every time I play them. Honorable mentions that have been around for a bit would be
Skullclamp,
Life from the Loam,
Brainstorm,
Faithless Looting, and
High Tide.

- Narset's Reversal - Blue does control really well of course, but this one is just the swiss army knife to end all swiss army knives.
This one is up there for me too. Borrow someone's
Cultivate, wreck someone with their own
Swords to Plowshares meant to wreck you, combo with your own
Turnabout. Sweet card.
It's a struggle not to put crop rotation and tithe in there too. 
Most of these have become my favorites because they are in my favorite deck.
