As mentioned in the title, this deck's strength is that of endurance:
Mark: death
10x gravity pillar
6x poison
6xarmagio
3xgravity pull
2x plague
1-2x gravity shield
1x arsenic (if you have one)
Strategy: this is not an offensive deck. essentially, your goal is to poison the enemy while using armagios to take the brunt of the opposing attacks
use plague and gravity pull to put down anything with heavy firepower (ex. dragons, shriekers, phase recluses, etc.) and use gravity shield to prevent anything big from getting through.
Weaknesses: being a slow, enduring deck, it dies easily against FFQ decks, and fast moving rainbow decks, and rush decks.
