Dani, the White Rose

Indestructible, Battle Cry (Whenever this creature attacks, each other attacking creature you control gets +1/+0 until end of turn.)
Dani can't attack or block if it has three or more anxiety counters on it.
Whenever a non-Bard creature enters the battlefield under an opponent's control, put an anxiety counter on Dani.
At the beginning of your upkeep, remove an anxiety counter from Dani for each other Bard you control.
