+sickness (4)
Trample, indestructible
Whenever Etali, Primal Sickness deals combat damage to a player, they get that many poison counters. (A player with ten or more poison counters loses the game.)
Enchant creature
When Motion Sickness enters, tap enchanted creature.
Enchanted creature doesn't untap during its controller's untap step.
Whenever you visit an Attraction, you may attach Motion Sickness to target tapped creature.
Enchanted creature gets -1/-1 for each Swamp you control.
Destroy target creature, then proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)
