Mortar, Wild Sentinel

When Mortar enters the battlefield, for each
opponent, you both roll a D20. For each roll
you win, target creature an opponent controls
loses all abilities and becomes a 0/1 plant token.
For each roll an opponent wins, they may put a creature from their hand onto the battlefield.
"I stared at the tree, and the tree glared back."
