Looking to do a pack to wheelchair, to help a buddy, could use ideas

Hey all, could use some hivemind ideas. I'm looking to help a friend of mine out. He's got Marfan's syndrome, and as a result, has a lot of pain doing everyday things a lot of the time. He has a run down and somewhat beat up manual wheelchair, and he's been trying to get on waitlists to get a donated electric wheelchair. He's on disability so most new ones cost more than he's allowed to have without affecting his monthly payments.

Him and I play Magic most weeks that we can, it's basically the one hobby he allows himself to partake in, and I'd like to find a way to use it and find a way to get him a wheelchair so he's more able to get out and do events with me.

So far, I'm thinking about doing some drafts with friends where I buy discounted boxes and take everyone's buy ins and put it in savings to get him a chair, but I think that will likely take a very long time. Another idea I had was somewhat like a pack to power but instead of ending with a Power 9 just end when I have enough to sell and get a decent shape chair. I was hoping for any other ways I might be able to have some fun while making this happen for him?

I'll probably just give up and sell a bunch of cards at some point to make it happen but I'd really (although selfishly) like to keep what I have for my own hobby goals. But yea, any ideas for fun ways to raise some money using Magic to help a friend out?
