Backstreet Blackhands

At the beginning of each player's upkeep, that player may pay any amount of mana. If that player pays an amount of mana greater than the number of Coin counters on this creature, that player gains control of Backstreet Blackhand and puts Coin counters on Backstreet Blackhand until the number of Coin counters on Backstreet Blackhand is equal to the amount of mana that player paid. If a player gains control
of this creature this way, this creature gains haste until end of turn.
