You may exile more cards than necessary for March of Otherworldly Light's first ability, but you can't reduce the mana it costs to less than this way.
(2/18/2022)
For example, say you wanted to choose a target with mana value 6. You need X to be at least 6. You could choose to cast March of Otherworldly Light by paying
6
. You could also exile white cards from your hand to reduce that cost by
2
 for each one. If you had a reason to, you could even choose a greater value for X.
(2/18/2022)
The mana value of March of Otherworldly Light while it's on the stack is the value chosen for X plus 1, no matter how much mana you actually paid to cast it.
