Apart from varying our converted mana costs to maximize our odds of hitting a creature with each Death's Oasis creature, the most important aspect of building around Death's Oasis is making sure we have ways to make our own creatures die for value
This Phyrexia: All Will Be One Commander Deck set includes 1 ready-to-play deck of 100 Magic cards (2 traditional foil legendary cards, 98 nonfoil cards), a 2-card Collector Booster Sample Pack, 1 foil-etched Display Commander (a thick cardstock copy of the commander card with foil etched into the card's border and art), 10 double-sided tokens, 1 deck box (can hold 100 sleeved cards), 1 Life Wheel, 1 strategy insert, and 1 reference card
You may cast a spell for its freerunning cost provided that youve done combat damage with an Assassin or your Commander that turn
Having it on a stick is greatif you dont need to sweep out the weenies, it can still swing, block, and sacrifice to deal an extra 2 to finish off a creature damaged by something else (perhaps from combat)
C: A playable commander card, not great, maybe you're running it because of budget reasons
