UG Madness

A tempo-aggro deck built around the madness mechanic. UG Madness turns discard into an advantage — every card you throw away becomes a free creature or a cheap counterspell.

Wild Mongrel is the heart of the deck. A 2/2 for 1G that gets +1/+1 and changes color whenever you discard a card. But the real power is what you discard: Basking Rootwalla has madness 0, meaning you cast it for free when you discard it to Mongrel. Arrogant Wurm has madness 2G — a 4/4 trample for three mana at instant speed.

Careful Study is a one-mana sorcery that draws two and discards two. On turn one, it can put two Rootwallas into play for free. On turn two, it sets up a turn-three Arrogant Wurm off a Mongrel discard.

Circular Logic is the deck’s signature counterspell. It normally costs 2U, but its madness cost is just U — discard it to Wild Mongrel, pay one blue mana, and counter their spell. The opponent plays into open mana at their peril.

Daze counters a spell for free by returning an Island. Combined with Circular Logic, the deck can protect its threats without keeping mana open.

Aquamoeba is a second discard outlet — a 1/3 that swaps power and toughness when you discard, becoming a 3/1 attacker. Frantic Search draws two, discards two, and untaps three lands — it’s essentially free and triggers madness twice.

Wonder is never cast. You discard it to Mongrel or Careful Study, and from the graveyard it gives all your creatures flying. A flying 4/4 Arrogant Wurm is nearly impossible to race.

Roar of the Wurm costs {6}{G} to hard-cast but only {3}{G} to flash back from the graveyard. Discard it early, flash it back later for a 6/6 token.

UG Madness is aggressive but interactive. It applies a fast clock while holding up permission — the opponent can never tap out safely when Circular Logic and Daze are live.
