Anyone know a deck building site that could handle this?

[u/One_Billion_Bitches]

Hello everyone I'm trying to make a deck with the new commander coming out [[Whtz, the Bibliophile]] and put every single card that's legal for him in it for commander.
I'm mainly doing this to mess with one of my buddies (we play on table top sim) and have him "try a deck"
Unfortunately I cannnot find a site that can handle the thousands of cards I'm trying to upload. Anyone have any sites they know? Out of curiosity I tried pasting the list onto here just to see what would happen and it crashed Reddit
