Absolute Annihilation

Choose one — • Abrade deals 3 damage to target creature. • Destroy target artifact.

All creatures have haste.

Whenever a player casts a spell, that player discards a card.

Destroy target creature. It can't be regenerated.

Sliver creatures you control get +3/+3.

All Slivers have "When this permanent enters, you may fateseal 1." (To fateseal 1, its controller looks at the top card of an opponent's library, then they may put that card on the bottom of that library.)

All Slivers have "{T}: Tap target permanent."

Sliver creatures you control have "Whenever this creature attacks, it deals 1 damage to any target."
