Hist-Tree Elder

Defender
Each other Argonian you control enters the battlefield with a +1/+1 and a vigilance counter
on it.
Whenever an Argonian you control leaves the battlefield, if it had counters on it, you may put
those counters on Hist-Tree Elder.
At the beginning of combat on your turn, move
any number of counters from Hist-Tree Elder
onto other Argonians you control.
