Ignition, Special Tea Brewer

At the beginning of your upkeep, put a colorless artifact tea token with "{t} Sacrifice this artifact:
Flip a coin. If heads, add {r}. If tails, target
creature you control gains haste until end of
turn." onto the battlefield.
"Babs, how can we scam our way into getting one of
those teas? What do you mean we can just ask? That's
no fun!"
