Jhin, the Virtuoso

Whenever a spell you control deals damage to
an opponent, put a Reload Counter on Jhin.
Then if Jhin has four or more Reload Counters, choose an instant or sorcery card
from your graveyard. Reveal it and put it back into your hand. Then deal damage to any
target equal to the chosen spell's mana value. Remove all Reload Counters from Jhin.
