pokemon card professor kukui (128/149) [Sun & Moon: Base Set] During this turn Professor Kukui #148 Prices |

Careful not to get your lores mixed up

Whenever you discard an Island, Pirate, or Vehicle card, create a tapped Treasure token

Mox Sapphire doesn't do anything more than provide a single blue mana, but the fact you could play as many of these artifacts as you wished on the first turn meant it was theoretically possible to have far more mana than your opponent if you received a lucky draw

On average RDW will have to spend one mana per card which will do 2 damage (including lands that is, the spells alone have a slightly higher mana cost and average damage output but it is easier to work in whole numbers and so the inclusion of the lands makes it so near to 2 damage for 1 mana you can forget the fractions)
