By playing cards like Sloppity Bilepiper and Heralds of Tzeentch, you can hope to hit cards that generate you even more value on hitting the battlefield, such as Chaos Defiler and Lords of Change
Besides that, you need to know that mana cost (which is used to determine mana value) is a copiable value
As such, in calculating the value of the cards in the set, I'm trying to use the number that I realistically think I can get for the card tomorrow (this is important because new sets tend to decrease in value quickly)
my partner Wendy is a fan of the show and has had me watch maybe ten episodes, which I certainly enjoyed, and it gave me a feel for the flavor behind the card mechanics of many of the Doctor Who Commander cards and The Doctors in particular
It perpetually loses this ability
Long gone are the days when you just build your mana pool to play your big cards
