Brynn, Stoner Royale

Whenever Brynn or another stoner enters the battlefield, create a joint token. (They're artifacts
with "{2}, Sacrifice this artifact: all stoners you
control become stoned and get +1/-1 until end
of turn.")
Whenever Brynn becomes stoned, choose one
that hasn't been chosen this turn—
•Scry 2 then draw a card.
•Deal 3 damage to any target.
•Put 2 +1/+1 counters on target creature.
