Aura Gnarlid and its cousin Rabid Wombat are old favorites of mine that havent much play, because they couldnt make an appearance with Zur, the Enchanter
They are in most decks that can run them, even decks with no need of the fixing sometimes run them, be it for the thinning, the graveyard filling, or the shuffles
Mirroring the Rise of the Floodborn release, theres only two Starter Decks for Into the Inklands : Amber and Emerald (Pongo and Peter Pan), plus Ruby and Sapphire (Moana and Scrooge McDuck)
The downside is that you have to spend energy equal to the mana value of the original creature you copied
The Temur see themselves as a pack, their bonds more primal than the Abzans
Similarly, commanders like Yuriko, the Tiger's Shadow can deal higher damage with a higher concentration of split cards
