Etali's Favor

Aura power has always been priced against the two-for-one problem: spend a card enchanting a creature, lose both when the creature dies. Discover 3 is the mechanic that reprices that risk. The buff itself is deliberately modest, a small stat bump and evasion that would be filler on its own; the real payment comes on entry, when the Aura digs to a free spell and either casts it or banks it in hand. Once the Aura resolves and that trigger fires, the card has already replaced itself, so removal aimed at the enchanted creature afterward costs you a slightly upgraded body rather than a whole card. The catch is the window before it resolves: an opponent who kills the target in response leaves the Aura with no legal creature to enchant, so it never enters, the Discover never happens, and you eat the full blowout. The reward is contingent on the Aura sticking, which is exactly the tension a design like this trades on. Think of it less as a pump enchantment than as a cantrip that leaves a residue on the battlefield, and note that the free-cast clause rewards a curve that stays under three mana value: the more of your deck sits at or below the threshold, the more reliably the hit lands on something worth casting. The trample keeps the marginal +1/+1 from being chump-blocked into irrelevance, closing the loop on a card whose job is to convert a low-impact enchant into velocity.
