when you discard a card draw a card mtg Tricks Necropotence

The Fire Crystal makes your red spells cheaper, which helps you to double-spell and keep turns explosive, and it also lets your creatures attack the moment they hit the board, so you stay on the front foot

I currently also have a package for looping Ao, the Dawn Sky with Nim Deathmantle, (one of my favorite things to do in Orzhov) in conjunction with cards like Teysa Karlov and Ashnods Altar to vomit your whole deck onto the table

Similarly, a Queens Agent as a 4/4 could potentially catch you up in notoriously uninteractive Ixalan, while a 3/3 often wasnt enough to blunt an assault (and was vulnerable to too much removal)

If target dies this turn, it is removed from game entirely and cannot be regenerated

so it's a question of if you'd be in the market to pay
