animate dead mtg card it loses enchant creature card in a graveyard and gains enchant creature put onto the battlefield with this Aura Animate Dead · Eternal Masters

I remember calling out to Dave Humpherys, who was at the time the lead developer of the set (Dave, Billy Moreno, and Ben Hayes were each the lead developer for a while Unstable was in development for years)

You may sign me up for bouncy enchantments with great enters-the-battlefield triggers, to include a bunch of them from this very set

Blizzard Brawl A simple fight spell on the surface, Blizzard Brawl becomes a brutal removal and protection combo in snow decks

Soltari Guerrillas You can redirect the 3 damage if Soltari Guerrillas attacks and isnt blocked, which can be a form of repeatable removal

Theres a huge drop from Koskun Falls, an admittedly niche playable, to the next most powerful cards in the set
