Gideon, Ally of Zendikar Mechanic

[fmartel]

Hello all, I'd like to know if I get the machanic of Gideon right...

His first ability is to transform into a Soldier Ally (still being a Plainswalker). Would that ability trigger all other Ally, Rally trigger ?

nevermind, I foud the ruling....
Found on MTG Gatherer.

Gideon’s first ability doesn’t count as a creature entering the battlefield. Gideon was already on the battlefield; he only changed his types. Specifically, your rally abilities won’t trigger. (Of course, Gideon’s second ability will cause rally abilities to trigger.)
