actually, no. time walk's restricted. use panoptic mirror and temporal extortion

if you really want infinite turns, combine Isochron Scepter with Time Walk
blanchwood armor would get the effect. snow-coverd forests are still forests, just with the supertype snow. use the snow forests to make this better. and if you wanted to use a giant aurochs herd, you might put veteran's armaments on one so you get +2/+1 for every other attacking auroch, and maybe runed stalactite to make a non-auroch into an auroch.
also, you can give this deck an infinite combo if you add imperious perfect and staff of domination. you have to have atleats 5 elves in play, but then you just keep tapping and untapping priest of titania and staff of domination to get infinite mana, in the pool, then use imperious perfect, well wisher, and staff of domination again to get infinite 2/2 elf tokens and gain infinite life.
