Kor Bladewhirl
Creature — Kor Soldier Ally
Rally — Whenever this creature or another Ally you control enters, creatures you control gain first strike until end of turn.
The high-pitched whirl of a hook is the only battle cry she needs.

The List (PLST)
• #BFZ-34Rulings
When an Ally enters the battlefield under your control, each rally ability of the permanents you control will trigger. You can put them on the stack in any order. The last ability you put on the stack will be the first one to resolve.
(wotc • 2015-08-25)
If a creature with a rally ability enters the battlefield under your control at the same time as other Allies, that ability will trigger once for each of those creatures and once for the creature with the ability itself.
