I take it you can't teleport hunting packs right? Personally I'd teleport my buffed Bastiladons so they can tie them down, while the rest of your army moves up.
Teleporting an immortal snake carrying bastiladon is brutal. Get it on an objective and start laughing
The pack is two units, so with the Seraphon teleport ability you can teleport the skink handlers (as they only Need to be in range). The salamanders you summon. That even leaves you with another teleport that turn for your Bastiladon If you take the warlord trait. Next turn leave bassie in place and teleport both the salamanders and handlers to another target unit. The teleportatie can be used every turn. Use it every turn them
