Malevolent Rumble log messages could be clearer

When Malevolent Rumble is activated the log messages accompanying that aren't very easy to parse through.
First, it says which cards have been revealed off of it, fair enough.
Then, it declares that a card has been moved from deck to hand, without specifying which one.
Then, it lists the remaining 3 cards as going to the graveyard, one by one.
Overall, while technically all of the information is there, it's presented in a not too easy to read through manner.

Locate the Malevolent Rumble implementation and inspect the log messages emitted when it reveals, moves, and sends cards to the graveyard. Improve the presentation so each card movement is identifiable and the sequence is easier to parse, then verify the resulting logs in the relevant game flow.
