Sindragosa, Frostbrood Queen

Flying
When Sindragosa deals combat damage to an opponent,
put a stun counter on up to X target creatures, where X
is Sindragosa's power.
When Sindragosa attacks, other dragons get +X/+0 until
end of turn, where X is the number of stun counters on creatures defending player controls.
"You are fools to have come to this place! The icy winds
of Northrend will consume your souls!"
