13 pillar is definitely enough to power the dragns, very widely tested with unupped deck myself
3 trident to ensure an ealy one, and like someone mentioned, even it gets stolen as long as it has not earth, you are fine
And of coz, learn to not play the ice shield if you know a steal is headed your way
trident cost + enchante artifact is simply tooooo high for your mark to keep up
And waiting for that single pillar to aid you is very inconsistent
