The one im using atm is (95%)
Atlas
2 Irradiated Infantry
Tiamat
Predator
Hunter
Burrower
Stealthy Niaq
Aquabat
Mortar Bunker
Full Power
Another one (about 80%):
Dracorex
3 Sabres
tiamat
predator
Obsidian
Fortifier
Aquabat
Mortar Bunker
Harbor Command (Another Mortar bunker would be better in most situations, dont got one..)
Another deck that works quite well (basically my oluth deck):
Dracorex
2x Pyro Rig
Howitzer (only if you use CC, useless if unrallied)
Bolide
2x Aegis
Poseidon
Nimbus (nullifies most enemy attack, better than obsidian cause of intruder/ shapeshifter mimicig the strike)
Mortar Bunker/ Command Centre (less siege, more power...)
EMP (use it if there are many assault cards on field/ if intruder shows up in front of something weak, cause if it lives it mimics bolide)
Play Pyro Rig ( or sth similiar if you replaced it) first, then get howitzer on 2nd. after that use aegis or poseidon if he played a structure. After that, try to get Bolide out to clear the field
