For the most part, though, this test of looking at previously banned cards should let us zone in on the cards most deserving of your attention
Getting a PK that can kill in one or at the most two hits is a great way to end games
The ability to grow is cool, but not amazing and frequently irrelevant (great with Hurricane though)
Three mana is a bit steep to cast it from your hand, but potentially harmonizing it for one makes Roamer's Routine a worthwhile mid-pack selection in Draft
Totem-Guide Hartebeest and Heliod's Pilgrim are both cheap creatures that act as MTG tutors for aura cards, letting you find the removal auras in your deck that Light-Paws can't summon, while Auramancer and Archon of Falling stars can pull important auras back from the graveyard
I havent played this card onto a board where I have less than five mana already available, so this can often stick around for quite a while accruing value in the form of not dying
