Guerrilla Tactics deals 2 damage to any target.When a spell or ability an opponent controls causes you to discard Guerrilla Tactics, Guerrilla Tactics deals 4 damage to any target.
First strike, protection from black and from red (This creature deals combat damage before creatures without first strike. It can't be blocked, targeted, dealt damage, or enchanted by anything black or red.)
Mortivore's power and toughness are each equal to the number of creature cards in all graveyards.: Regenerate Mortivore. (The next time this creature would be destroyed this turn, instead tap it, remove it from combat, and heal all damage on it.)
Each noncreature artifact is an artifact creature with power and toughness each equal to its mana value. (Equipment that's a creature can't equip a creature.)
Flying (This creature can't be blocked except by creatures with flying or reach.): Vampire Bats gets +1/+0 until end of turn. Activate no more than twice each turn.
Haste (This creature can attack and as soon as it comes under your control.)At the beginning of the end step, return Viashino Sandscout to its owner's hand. (Return it only if it's on the battlefield.)
