Instant Madness

Rather than pay the mana cost for a spell, its controller may discard a card that shares a color with that spell.

Whenever a player casts an instant or sorcery card, exile it. Then that player copies each instant or sorcery card exiled with this enchantment. For each copy, the player may cast the copy without paying its mana cost.

Whenever you cast an instant or sorcery spell, you may put a charge counter on this artifact. If you do, this artifact deals damage equal to the number of charge counters on it to any target.

Each player shuffles their hand and graveyard into their library, then draws seven cards. Exile Time Reversal.
