I tried Googling it, but it's been 6 years since I was in college and it seems to be a couple classes ahead of what I took as a math major. Adsing integers and multiplying integers is always going to result in countable infinity, no matter how hard I try, from my knowledge.
In Magic: the Gathering, players can "add mana" by "tapping" a card, rotating the card somewhere between 0 to 90 degrees to show that its ability can't be activated again this turn, to "add N mana" of some color or type.
If a player somehow manage to find a way to "untap" the said permanent indefinite amount of times, or can present that there's some game action looping that grants you more mana than before the loop, it is considered that the player has "gone infinite" and with some sort of outlet for that "infinite" amount of mana and announcement of no interruption, it is generally considered game over.
This card, as you can see, doesn't cost uncountably infinite amount of mana to play, as its cost shows on the upper right corner. LET'S SAY THAT IT DOES.

Question:
Is it possible to say "I add N amount of mana "some amount of times" to make omega null amount of mana"?
