Epiphany Storm

Rummaging on a stick, and the cost structure is the whole experiment. Rather than printing the discard-then-draw filter on a body or a one-shot spell, the design grafts a repeatable rummage onto whatever creature you can keep alive, paying for the swap with both a red mana and the tap of the host each turn. That tap clause is the real tax: activating the ability commits the creature to filtering rather than attacking, so on offense you are usually choosing between the body and the engine. Defense is more forgiving, since a blocker can absorb a hit and still tap for the swap once combat is settled. The result is a slow card-quality tool that wants a graveyard payoff to make the discards matter, because draw-equals-discard is card selection, not card advantage. It sits in the lineage of repeatable filtering that runs through the various Looter creatures, but it inverts the math: instead of buying a dedicated filtering creature at full retail, you spend one mana to convert a creature you already have into one, betting the Aura's two-for-one risk (lose the creature, lose the enchantment) against the value of a permanent outlet. If it lands on a creature without summoning sickness, the granted ability comes online the same turn, so filtering can start immediately. The whole thing still rises or falls on whether the deck has something hungry enough for discarded cards to justify carrying an Aura whose value is locked behind a creature staying alive.
