  While resolving the triggered ability of Bramble Sovereign, you can't pay multiple times to have a player create more tokens.

  The token copies exactly what is printed on the creature and nothing else (unless that creature is copying something else; see below). It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and/or Equipment attached to it, or any non-copy effects that changed its power, toughness, types, color, and so on.

  If the copied creature is copying something else, the token enters the battlefield as whatever that creature is copying.

  If the copied creature has in its mana cost, X is 0.
• 2018-06-08
  Any enters-the-battlefield abilities of the copied creature will trigger when the token enters the battlefield. Any "As [this creature] enters the battlefield" or "[This creature] enters the battlefield with" abilities of the copied creature will also work.

  If the entering creature leaves the battlefield before Bramble Sovereign's ability resolves, use that creature's last known existence on the battlefield to determine the token's characteristics.
