Oracle Text

[Striding Shotcaller]
Reach
Whenever one or more creatures you control deal combat damage to a player, this creature becomes prepared. (While it's prepared, you may cast a copy of its spell. Doing so unprepares it.)

[Run the Play]
Put a +1/+1 counter on each of up to X target creatures. Those creatures gain flying until end of turn. Draw a card.
