They introduced 10 Mega Evolution Pokmon ex, new full art Trainers, and a brand-new rarity tier called Mega Ultra Rare (MUR) thats already commanding big prices on the secondary market
This doesnt necessarily mean you can only purchase your MTG MLP cards as collectibles there is one place you may be able to play these cards, and thats at a casual Commander table where you Rule Zero them in
While the new Commander Masters cards are obviously built to mostly bolster the latest decks - namely an Eldrazi one, a Sliver one, a Planeswalker one and an Enchantment one - some will also make other decks, albeit ones that have similar themes for the most part, a lot better
Adeline's power is equal to the number of creatures you control
I believe Slip Out the Back to be the best of them, but cards like Loran's Escape, Blacksmith's Skill, Revitalizing Repast, etc
