Uh so Alec decided to stick around and I guess making the clone was really expensive?
At Alex's level of magic he can basically turn time spent into wealth directly.
The wish version he is using came from Pathfinder, which as a principle took any spells that had XP values spells may have had, and converted them into GP value instead (either X ounces of gold coins, or so much diamond/gemstones) [mentioned earlier in the story: the joke about it all coming down to crystals for power(up) sources]
Even with that limitation intact, Alex could take whatever literal waste is lying around, and rearrange the carbon inside it into a crystalline lattice (aka a diamond) and then use that to cast wish to create up to the equivalent of 10,000 GP of any/all material goods he wants. (This is the minimum, using the most restrictive interpretation of wish with only what is specifically allowed.)
Alex also has the ability to overlevel his spell, breaking the normal limits. Something said in a pervious MHA snipped make me think he no longer needs diamonds as a material component anymore; that he can just spend his MP on a magical effect, including creation of material goods.
So the time spent isn't his personal time anymore, but the time it takes him to regenerate the MP.
@Mister Ficser If he is going to be offering boons to Izuku/Eri, he should consider Wish granted Inherent attributes.
The normal limit is +5 per attribute, but if he has Wish Lv. 200, that is probably at least doubled. On a scale where 10 is fit average, and 18 is normal human maximum. Spending 10 wishes each on 6-7 attributes (D&D doesn't include a LUK stat, but the Gamer system does) would make average to Captain America levels in body and mind. And cannot get dispelled away like a Locked spell can.
...this is also something he should consider doing for himself and Jinx/Kary in the main timeline. This is because his version of the System's missing Gamers Body means many of his Gamer given stats don't do anything. But the Inherent Bonus Attributes are something from a methodology that never possessed Gamers Body to begin with, And could be used by wizards to increase the attributes of nonmagical folks, and have it "just work"
So inherent bonus attributes, should fully interface with his base body/mind properly.
