Adding a couple of cards from Innistrad: Midnight Hunt and Innistrad: Crimson Vow is sure to power up the deck, and Necroduality looks to offer that in abundance
Cards like Queen Brahne, Red Mages Rapier and Sidequest: Play Blitzball can generate big rewards if you are able to get through, which makes the keywords from Coral Sword and Item Shopkeep very valuable
Then there's also Gatherer's language issue We discovered recently that Gatherer search fails for anyone from non-English regions
The only drawback is that it also deals 20 damage to itself, but the attack is cheap, so it's definitely worth it
In Limited drafts and tournaments, you would be able to take as many of the basic land as you wanted (and presumably we would send them out to TOs)
Most value you can generate is from attacking, and a pillowfort deck doesnt really attack enough to get full value
