Some big changes for the cube!

• Ninjutsu package - @Griff pointed out that these could be interesting for the flicker/self-bounce deck. Despite my skepticism that Griff is just trying to buff his favorite deck in this cube, I'm inclined to agree because it incentivizes the blink player to attack more aggressively than they might right now (the current build is basically just stall, generate value, and then win with fliers). The swaps here are just random cards that either haven't really performed or I don't find that interesting.
• Final Vengeance > Eaten Alive - mostly a strict upgrade (not enough enchantments in this cube for it to not be)
• Whitemane Lion > Rescuer Chwinga - Strict upgrade. Also the Chwinga is cute. No one bazingas the Chwinga.
• Compulsion > Trade Routes - Strict upgrade. Wish compulsion would work because I love the art, but I don't think it's ever been run in a deck in the ~6 months it's been in the cube.
• Militia Bugler > Containment Construct - Construct is too cool to not double up on, and Bugler a) has vigilance for no good reason (yes there's a flavor reason, but I hate vigilance), and b) has been a bugbear of the flicker deck for far too long; despite my efforts to nerf the deck, this card has continued to be a key value driver.
• Terisian Mindbreaker > Oskar, Rubbish Reclaimer - @Ahnkili pointed out at Vertex that this could be a trap to new players who don't realize that killing half your opponent's deck is actually giving them a gift. I do think there's probably a build where this thing is sick, but agree the risk of misinterpretation by less experienced players is too high for the card to continue being in the cube.
• Repopulate > Funeral Charm - Repopulate got played very little, and I ran Piracy Charm for a while and was sad to cut it.
• Oona's Grace > Rotting Rats - Despite having a ton of fun playing Grace in @PseudoTriangle's Lands Cube this week (and it being quite good there), I don't think it gets there in Penrose
• Lodestone Myr > Emberstrike Duo - I love the Myr a lot, and wish he was good enough, but the artifact deck has better things to be doing. I'm not sure Duo is right here though. I love the synergy with the red/black aggro deck, but is that interesting enough?

Grim Flayer has been updated to a version that has correct oracle text.

The other changes are some last minute swaps.

For being annoying and repetitive
