Someone new to the game is going to be looking at new cards where there is no such thing as
![Mana - 1 {1} {1}](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
being added to your mana pool. They will understand that <> is a type of mana just like
![Mana - Red {R} {R}](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
, and
![Mana - 1 {1} {1}](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
can be paid with any type of mana. If anything, confusion will be reduced because no one will thing you need to add
![Mana - 1 {1} {1}](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
to your mana pool to pay for a cost that requires
![Mana - 1 {1} {1}](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
. Once they are introduced to older cards (including cards from the same block, so great execution there) they will have to learn that "add
![Mana - 1 {1} {1}](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
to your mana pool" and "add one colorless mana to your mana pool" are older ways of writing "add <> to your mana pool," but there have been two ways of writing it for a long time and it hasn't been a problem.
