Invasion of New Capenna // Holy Frazzle-Cannon is a nice flexible removal and has the potential to become a great tribal support card as the Holy Frazzle-Cannon has Whenever equipped creature attacks, put a +1/+1 counter on that creature and each other creature you control that shares a creature type with it. Murderous Rider // Swift End is a great card since it is a Zombie, it combines target removal at instant speed for and self-recursion at library, so it has the potential to be used more than once
It nets a lot of cards and then pays you back if youre storming
Often, it will last until it is overwritten by another copy effect (if it copies another permanent on a future turn, perhaps)
Mishra's Bauble, one of the best eggs in Magic, isnt as broken, but being a 0-mana cantrip (even if the card draw is delayed) makes it a mainstay in Vintage and Modern
