A brief disclaimer: As someone who used to work in Magic R&D, I feel much more strongly about banning cards to make the format better than unbanning, but banning is a very tricky thing in a game like Magic where cards hold a lot of value
The main event uses Infinity Constructed format, with sets 112 legal and Hiram Flaversham Toymaker banned
If that doesnt sound too hot and youd rather sell directly to buyers, you can list the cards on online markets like TCGplayer, eBay, or the ChannelFireball marketplace
We could see removal spells represented by timely flourishes in combat, and token spells that signal the arrival of reinforcements
You get to kill all the creatures, draw a bunch of cards, and finish them off in style
Notably, if you put an Aura card onto the battlefield this way, it can't enchant Genesis Hydra
