The Dungeon Master

Fury of the Hare — Whenever you roll one or more dice, The Dungeon Master deals 2 damage to any target

Chaotic Spellcraft ~ Whenever you cast an instant or sorcery spell, roll a d20. This triggers only twice each turn:
1-10: Create a treasure token.
11-18: Scry 2, then draw a card.
19-20: Copy that spell. You may choose new targets for the copy.

Calculated Chaos — If you would roll one or more dice, roll an additional die and ignore the lowest result.
