Inoe, Seer of the Beyond

Inoe enters the battlefield with four plus X sight counters.
Remove a sight counter: Put a sight counter on
another target face-up card in any zone. Scry 1.
You may activate any ability of any card with a
sight counter on it, except for mana abilities. For
each sight counter beyond the first on a card, its
activation costs are {1} less. This can't reduce a
mana cost to less than {1}.
