AoS Chameleon skinks ambush

[Lurkaliska]

Hello guys

If I play a troop of chameleon skinks can I do this sequence?

Deploy: set in reserve
First turn: deepstrike
Second turn: hide
Third turn deepstrike
Fourth turn: hide
Fifth turn: deepstrike

So at the start of my fourth turn I have my chameleon on the battlefield so they are not slain but can I after movement phase hide them and deepstrike again in my fifth turn?

Or I can't put in reserve anything from the battlefield after fourth turn?

It only checks at the start of the fourth battle round. Your ambush sequence works.
