Cumulative upkeep - Exile the top card of your library
Dutiful Twinhorn gets +1/-1 for each card you own in exile.
When Vhon was young, he was chosen to guard the sacred burial grounds of his people. When the Frilian war tribes came, he was chosen to stand against them in battle. And when his horns had cracked from years of toil, he was chosen to join his ancestors in rest.

story's great. card's interesting. I dunno if it's good enough to be worth exiling 10 cards from your library, but at every step along the way it's a pretty impressive body for a 3-drop. I like how the accelerating effect of the cumulative upkeep means it's pretty hard to kill before it gets to that final 10/1. it's a shame to use exile though 'cause it means that even one card exiled for any other reason cuts off that form entirely and breaks the cohesion of the story. I don't know how to do this with counters without getting really ugly in practice, but I wish there was a way to localize the effect to the particular copy of the twinhorn, especially since one going all the way means that all the others in your deck are blank.
