War Room Holotable

Whenever one or more artifact creatures attack or
die add a charge counter to War Room Holotable.

At the beginning of your postcombat main phase
you may draw a card as long as War Room
Holotable has a charge counter. Then distribute X
+1/+1 counters amongst any number of creatures
you control where X is the number of charge
counters on War Room Holotable.
