The Sleg Fortress

Whenever a Dinosaur Soldier enters the battlefield under your control, create a token copy of it.

Dinosaur Soldiers you control get +0/+3.

When The Sleg Fortress enters the graveyard, choose one —
• Lose life equal to how many Dinosaur Soldiers you control.
• Destroy all Dinosaur Soldiers you control.
