Insidious Trojan

When Insidious Trojan enters the battlefield, you
may tap a number of untapped creatures you
control equal to its converted mana cost. If you
do, create a token that's a copy of it. Then an
opponent gains control of Insidious Trojan.
At the beginning of your upkeep, create a Spam
artifact token with "At the beginning of your end
step, this artifact deals 1 damage to you."
"We recommend burning all infected devices."
