mtg dragonstorm collector booster box Magic: The Gathering Tarkir 6 Case as well as the chance to pull one of 500 serialized Headliner cards Tarkir Dragonstorm Play Booster Case

If you can keep a steady supply of cards in hand, you can answer almost anything your opponent can throw at you

When this card destroys a Zombie monster by battle and sends it to the GY: You can Special Summon that Zombie monster

If you control a "Valkyrie" monster other than "Valkyrie Funfte": You can send 1 Spell/Trap from your Deck to the GY

Rather than 99 one-offs, you assemble ~8 themed packages (ramp, draw, interaction, payoffs, etc.)

Even with that Deathmark still has a lower hit rate than a Shock in cube, has no alternate utility, is sorcery, and will wind up a totally dead card in some matchups

Turning Urzas Command into a straight-up removal spell could tip this cards balance too heavily into controls favor
