Menace
When Massacre Girl enters, each other creature gets -1/-1 until end of turn. Whenever a creature dies this turn, each creature other than Massacre Girl gets -1/-1 until end of turn.

You may have Sakashima enter as a copy of another creature you control, except it has Sakashima's other abilities.

Menace

First strike, trample, lifelink
Stagger — Whenever Lightning deals combat damage to a player, until your next turn, if a source would deal damage to that player or a permanent that player controls, it deals double that damage instead.

If an effect would create one or more tokens under your control, it creates twice that many of those tokens instead.

Trample
Other Dinosaurs you control get +1/+1 and have hexproof. (They can't be the targets of spells or abilities your opponents control.)

As long as this artifact is untapped, each spell that would cost less than three mana to cast costs three mana to cast. (Additional mana in the cost may be paid with any color of mana or colorless mana. For example, a spell that would cost to cast costs to cast instead.)

Flying, vigilance, indestructible
Other permanents you control have indestructible.

Creatures you control have flying, first strike, vigilance, trample, haste, and protection from black and from red.

This creature gets +1/+1 for each other creature named Seven Dwarves you control.

Flying

As long as this artifact is untapped, each spell that would cost less than three mana to cast costs three mana to cast. (Additional mana in the cost may be paid with any color of mana or colorless mana. For example, a spell that would cost to cast costs to cast instead.)

If you control a commander, you may cast this spell without paying its mana cost.

Rockslide Ambush deals damage to target creature equal to the number of Mountains you control.

Counter target spell that targets a permanent you control.

Avoidance — Whenever you cast a noncreature spell, exile up to one target nonland permanent you control, then return that card to the battlefield under its owner's control.
