It's great, but you need to run it in the right deck, not every deck can get cards into the graveyard and some want to save them for reanimation like Living Death or recursion like Eternal Witness
If you enchant it with Sinking Feeling, you can pay one mana to put another -1/-1 counter on and untap it
Phlage, Titan of Fires Fury is also notably capable of drawing a card off Haliya on its own
Not every card has to be better than another one, but if the strictly better one came out only nine months before, maybe the new, bad one shouldnt be printed
Flickering Aang, at the Crossroads to spew creatures seems like a decent start to a deck, especially with mass-flicker cards like Eerie Interlude and Hide on the Ceiling to flicker Aang and all your goodies
