Her ability exiles instants from the graveyard, and she casts them when she attacks
10/10 in terms of mechanics and lore, and given the popularity of the Weeping Angels, I'm not surprised to see this around $20 in the showcase treatment
She's a fan-favorite character, for sure, so it makes sense to have this tie-in, especially considering a brand-new Lorcana set has just been released
These decks were Amber and Amethyst (featuring Moana and Mickey Mouse), Emerald and Ruby (Cruella De Vil and Aladdin) and, lastly, Sapphire and Steel (Aurora and Simba)
When 70% of instants and sorceries in my cube are 1 or 2 mana and the average CMC of such cards is about 2.5 (realistically a lot lower as so many of the high cost cards have delve or pitch and alternate costs) you start to appreciate how good four mana and higher spells must be
Typically, well use TCGplayers handy Market Price feature for this, however, not so today
