"Hoard" is written correctly, I think. It is a cycle, though a small one; the uncommon and common cycles are one-of-every-colour, while this is the two "colours" less common (artifact and non-basic land) so they are rare. I agree that they aren't tied together like the others, so calling them a cycle is really stretching its meaning.
The Chalice you posted doesn't increase the "growth" of hoard counters, so it doesn't do what was originally intended. It is more like the "Recharging Unit" I posted in the original thread (

Artifact Sac This: Put a hoard counter on every permanent with accumulate). I like this idea too, but I think it shouldn't be able to distribute every counter at once, and I would really miss a card that adds some speed to the growth of those cards, because otherwise they might become a bit predictable without some interaction. I would word your proposal the following way:
Chalice of Plenty

Artifact
Chalice of Plenty comes into play with X hoard counters on it.

: Move a hoard counter from a permanent you control to another permanent you control with Accumulate.
Is this okay? It makes a complete redistribution possible, so it might need a higher cost than
