I have been recently looking at the top cards in each color for card draw of all time for kitchen table play like Commander, Five Color, Highlander, and Pauper/Peasant and all multiplayer formats too
Just like how those clamouring for Hogaak, Arisen Necropolis or Faithless Looting to get banned in Modern a couple of months ago should have been registering the deck all along, if you want to win and genuinely believe a card needs banning in Pioneer, then you should be playing it and trying to break it
This style of counterspell has played reasonably well of late, and this one has the Lesson subtype
Astarion, the Decadent is the ultimate top-end lifegain card, and theres a big difference between gaining 10 life versus 20 or more in a single turn
This can be very beneficial in stopping your opponent from getting close to winning and can make them swing into one of your characters and potentially be banished as a result
One of the most powerful things you can do in Magic is play cards for free, and Demon of Fates Design lets you do that with enchantments
