I really like the Witherbloom school cards from Strixhaven: School of Mages that play up this strategy, and you can find them in Scryfall by searching for wm:Witherbloom for watermark, Witherbloom
The creatures in it must be transported to the graveyard through the combat phases or destruction
OK, now that all of that is out of the way, lets get to the part that you probably actually care about: printing your own proxy cards
The casting cost for the burn effect seems a bit off, but this is probably the lowest that we can realistically get because it's going to become too busted at two mana
Think: your mana dorks now tap like Command Beacon, Strip Mine, and Ghost Quarter
Casting Seasons Past two or more times should be enough card advantage to seal the deal
