It's a ton of fun to play, bouncing Flickering Ward and Conviction back to hand, replaying on whatever target creature needs them, drawing a card, creating tokens, gaining life, do it all over again
Casting spells from exile, or at least outside of your hand, does have synergy in the right deck, so I wouldnt call this a dud
This would be a nice ability to be able to pick up incidentally
As players engage with this set, they are immersed in a narrative of valor, sacrifice, and the eternal struggle between mortals and the divine
While I dont think thisll climb as high as The Ozolith (its not an artifact), I think that itll end up being a $10+ card by the time Dominaria United releases
With all this artifact play going on you want redundancy, resilience and protection for your little artifacts and Toph, the First Metalbender, Mendicant Core, Guidelight, and Inspirit, Flagship Vessel do so very nicely
