You can even run a bit of a Stax build in Green with cards like Root Maze and Winter Orb since this untaps your lands for you and leaves theirs frosted
I also really like the way that this card plays in graveyard decks that include Bone Miser and other other enablers
These dont always work, but they often have great targets, whether thats effectively countering a counterspell, pointing removal towards someone elses creature, or best case, making a Time Warp target you instead
Scar, Vengeful Lion will help with card draw, as every time you challenge an already damaged character, you can take the top card of your deck and tuck it safely into your hand
But does it have the potential to rocket you ahead at a critical moment
WOTC did a fantastic job with the flavor here
