There are two old school cards I want to highlight: Backlash and Delirium
The combat damage downside here is significant, but manageable
Again, no brakes like once per turn, or a bigger life loss, 1 is nothing here, and then you didn't spend mana or tap or do anything else, all of the card flow happens
Much like 2017, 2020 has become the year of the Reserved List buyouts
Just like tracking their graveyard size and playing 5D future library size Chess isn't what people play Magic for, starting at UUUB open and trying to route through Spellstutter Sprite, Cryptic Command, Mistbind Clique, Scion of Oona, and later Agony Warp just broke people
Its very hard for me to just experience a card unto itself
