I think Monte Carlo would benefit from having either an extension of the Markov Chain duration (like the Bad Juju catalyst) or perhaps an increase on the number of stacks of Markov Chain. Side note; a dark/night themed ornament would be nice and could be named after staying up all night gambling, possibly in an illicit manner. Maybe "Illegal Poker" could be the name of said ornament, or a perk that improves melee damage as suggested below.
