Dark Depths (Topper) [Ultimate Masters Box Topper] Goblin Assassin Wood Elemental's power and toughness

Wood Elemental's power and toughness are each equal to the number of Forests sacrificed as it entered the battlefield

where X is the number of Swamps you control

you may exile any number of tokens created with Tetravus

and the second player controls the first player during the first player's next turn

Is it my gluttonous lust for power
