I've recently been inspired to make a Grixis deck, and cause I build every deck with the intent on being a massive tool, I want it to involve cards that make my opponent discard cards and sacrifice permanents, with a side of unsummoning.
Cards I have in there already are;
{Thraximundar}
{Crosis, the Purger}
{Nicol Bolas}
{Unscythe, Killer of Kings}
What other spells, creatures and combos would be good?
{Grimgrin, Corpse-Born} forces you to sac. But he still destroys a creature plus he can get über big!
Yeah, I'd come across that.
{consult the necrosis he's}
{slave of bolas}
{cruel ultimatum}
{grixis grimblade}
{pestilent kathari}
{insurrection}
{Abyssal Specter}
This was reprinted in m13 but my phones being a dick and I can't search for the current one.
{Cruel Ultimatum} is never fun for your opponents if it resolves
