Blazing Rootwalla

Madness is the whole pitch: discard this to any outlet and it costs nothing to bring back, turning a card you were pitching into a free 1/1 the moment it hits exile. That price is the point. A one-drop that arrives for zero mana while you dump cards to some other engine is not paying rent as a creature; it is paying you to advance whatever your graveyard cares about, be it threshold, delirium, a body count for aristocrats, or fuel for reanimation. The pump ability is the vestigial half of the design, a color-shifted echo of Basking Rootwalla back when a 1/1 that could attack as a 3/1 was a real consideration. Here it is a mana sink you almost never reach for, because the card's value was already banked when it entered for free. What makes it durable is that its job never demands anything of the deck beyond a discard outlet: build around wanting to throw cards away, and this rewards you for the discards you were making regardless, refunding one of them as pressure on the board instead of a card lost to the yard.
