This is a kill on sight Commander, and one that your entire table may need to keep under control
Saheeli, Filigree Master You can +1 her to scry 1 and then tap an artifact you control and draw a card, so scry into card draw is quite nice
All other cards in the deck must share their color with the commander
If a sorcery would enter the battlefield, it remains in its previous zone instead
Casualties of War is solid removal that can hit practically anything, but for six mana you'll usually find yourself holding it waiting for the opportunity to use each option
If it's hitting for 40+, it's probably hitting for weakness damage (again: it's doubled for the rules in this game) After addressing that, I wanted to say there appear to be at least a few more serious bugs present
