Wedge is flying in formation with Garven, Thane, and Sabine
And all 3 x wing pilots have swarm tactics.
Wedge shares his initiative at the start of engagement phase, and others swarm tactics trigger at the same time.
Wedge gives his ini 6 to thane, thane becomes 6 and give his ini 6 to garven.... after all, everyone becomes I6 at the start of engagement
So...is this legal?
