'Coercion', The Storm Cutlass

Can only equip to Em, Daughter of Storms.
Equip 2.
When equipped creature deals combat damage
to a player, you may create that many 'Treasure'
tokens with 'Sacrifice this token to add one mana
of any colour to your mana pool'. If you do so,
reduce the combat damage to 1.
Let me remind you what you're paying me for.
