Rain, Skilled Snatcher

Whenever a rogue enters the battlefield under
your control, put a Heist counter on a target
artifact you don't control.
When a rogue you control deals combat damage
to a player, you may take control of an artifact
with a Heist counter on it that defending player
controls until the end of turn. At the beginning
of your end step if you control 10 or more
artifacts with heist counters on them you
win the game.
