Emissary Green - 4G
Legendary Creature – Human Advisor (Rare)
Whenever Emissary Green attacks, starting with you, each player votes for profit or security. You create a number of Treasure tokens equal to twice the number of profit votes. Put a number of +1/+1 counters on each creature you control equal to the number of security votes.
3/3
Attacking with a vanilla 3/3 on ~turn 5 depending on ramp doesn’t seem good but assuming you can, this seems like it could get kinda crazy? Most likely you’d get 6 treasures (!) and a +1/+1 counter on your whole board if everyone is still playing.
