mtg commander deck box ultra pro Masters Sliver Gravemother 100+ for Magic: The Gathering Alcove Flip Deck Box Lightning Army of One Ultra Pro 100+ Deck Box

This card is reminiscent of Slicer, Hired Mercenary, but has a mid and late game because of the five Treasure steal effect

It makes creatures that share a color unable to block creatures of a given color for one turn

And once each opponent has a counter we can proliferate the poison until they die with cards like Flux Channeler and Experimental Augury

It's often compared to the now-banned Hullbreacher as being a 'feelbad' or 'unfair' card, but as long as your playgroup is fine with it, it can be a really powerful creature to use

While this isn't as powerful of an effect as Krenko, Mob Boss has, it's able to take advantage of assorted buff effects in the deck to scale quickly, and with Coat of Arms it can match or exceed the commander's output
