With tiny creatures and tokens being cornerstones of white mana since the very beginning of Magic, Mentor of the Meek has been a staple card ever since it was first printed in Innistrad
Uro, Titan of Natures Wrath Uro, Titan of Nature's Wrath isnt as dominant in Commander as in Standard or Modern, but that doesnt mean it cant hit hard
Gravebind is a really awesome illustation, I don't know what you're talking about
One line to keep in mind is casting this at the start of the turn you want to win the game, forcing your opponent to either counter this or let you combo off in peace
I probably would have played both a Snapcaster Mage and a Brainstorm (over the See Beyond) if I had access to them but they were in other people's decks
Anyways, this is a big improvement on the "Winter" part of this card from its first printing
