mtg christmas commander deck 3-Row Trading Card Box - Oak Maple Cherry 10 festive Magic: The Gathering

In addition to its rather beefy combat stats, Kroxa and Kunoros lets you effectively escape a creature from your graveyard to the battlefield by exiling five other cards

Exsanguinate is a perfect card for this Rakdos commander, as it gives you a ton more life to play around with and more than cancels out any life you spent to get a discount on it

6 Abaddon The Despoiler Straight from the Warhammer 40,000 Commander decks, Abaddon the Despoiler doesnt have cascade itself, but its Mark of Chaos Ascendant ability instead gives all spells in your hand cascade so long as their casting cost is less than or equal to the amount of life all your opponents have lost this turn

That gets you 24 ready-to-mix Jumpstart boosters, with every pack including 20 cards, all the lands needed to play, and at least one Rare or Mythic Rare card

Its as simple as that

In short it invalidates mana rocks while also countering free spells
