The roles the Forge fills for this commander, and how many cards of each.

• 14× Mana value at or above the floor — for a cascade commander a cheap card is a DEFECT, not a bargain
• 20× A card that is CAST to trigger the commander — reanimating or blinking it does not count
• 6× Put +1/+1 counters on creatures you control, or multiply the ones already there
• 5× Actually remove one problem permanent — preventing its damage is not removing it
• 9× Find the exact card the plan needs

• 2× Keep a permanent you control alive through removal
