Miracle Time Walk seems like trouble, especially with a deck built around drawing cards and deck manipulation. Hey, look, they're both blue. Truthfully, I'm expecting banning in Legacy within a year. Legacy's drawing engines are far more manipulation than raw draw.
The rest of the cards don't interest me much. Heron guy is just a better power level Tajuru Preserver, and I don't remember that being particularly good, despite the affordable 1G cost.
Oh, wait, Griselbrand as an EDH general. There's a scary thought, and probably also suicide.
I was thinking the samething. Blue has always had the power to manipulate draw power (index, ponder, brainstorm, etc etc) and Miracle Time Walk, I don't doubt someone will find a way to abuse the living s**t out of this card. While I don't play Legacy anymore, I do hope that this card gets banned or at least restricted because while it is powerful, at least if it's restricted it will at regulate the abuse.
Lol Plus some return to deck from graveyard effects, empty your deck enough and Miracle Time Walk ftw.

Seems like a nice Standard set-up abuse for it. Could be wrong, but oh well... yeah it is a bit over the top when someone does figure out how to abuse it in some weird loop. Probably Legacy and lower have the card pool needed for the task.
