Artem the Treacherous

When Artem the Treacherous enters the battlefield, all players must offer Artem his
cigarette.
The player Artem chooses has hexproof.
(You can't be the target of spells
or abilities your opponents control.)
If Artem is not present, creatures you control
have trample. Creatures your opponents control
lose trample and can't have or gain trample.
