Ruby Weapon

Indestructible, First Strike, Protection from Blue and Green

Ruby Weapon can’t be blocked unless defending player controls an untapped red permanent.
Whenever Ruby Weapon enters the battlefield or attacks, exile up to one target creature an opponent controls. That player creates a 0/1 Sand token.
If Ruby Weapon would leave the battlefield, you may exile two Mountains instead.

“It emerges from the desert only to erase those who dare challenge it.”
