Giulia Giovanni Abruzzina
Unique wraith with 1 life. 0 strength, 0 bleed.
If a Giovanni you control is in combat, you can lock Giulia before range is determined to set the range for the round to close.
Rulings
Once the range is set, no other effect can be used to reset the range that round, but other pre-range effects can be played afterwards. Skip the Determine Range step for that round.
If another effect was already setting that round's range (e.g. Neutral Guard), that effect has priority.
