Siege Rhino (!!!)
Tasigur, the Golden Fang
Courser of Kruphix
Wingmate Roc
Dragonlord Ojutai
Dragonlord Silumgar
Monastery Swiftspear
Den Protector
Brimaz, King of Oreskos
Boon Satyr + most creatures enchanted by it
And that's just cards that already see extensive standard play. Let's list a few more from Origins that have realistic potential:
Archangel of Tithes
Kytheon, Hero of Akros
Vryn Wingmare
Jace, Vryn's Prodigy
Mizzium Meddler (which might actually be a downside)
Despoiler of Souls (which isn't great, but it's something)
Liliana, Heretical Healer
Abbot of Keral Keep
Embermaw Hellion
Goblin Piledriver
Woodland Bellower
So yes, there are targets for this card.
