Sheriff of Safe Passage

You can’t cast a plotted card on the same turn it became plotted. On any future turn, you may cast that card from exile without paying its mana cost during your main phase while the stack is empty.

If Sheriff of Safe Passage enters the battlefield under your control at the same time as one or more other creatures, it doesn’t take those creatures into consideration when determining how many +1/+1 counters it enters the battlefield with.

If you’re casting a plotted card from exile without paying its mana cost, you can’t choose to cast it for any other alternative costs. You can, however, pay additional costs, such as kicker costs. If the plotted card has any mandatory additional costs, those must still be paid to cast the spell.
