That's not bad, but this card also has Escape, a brand-new mechanic, which costs 4 mana and 5 exiled cards
There are still a lot of common abilities that are brand-new to me scry, flash, lifelink, this thing where I earn the citys blessing, legendary cards that have four different potential abilities but most of it gets helpfully defined simply by right-clicking on a card
Certain cards require speed to perform actions or use speed to give benefits
Then, place the rest at the bottom of your deck in any order and if your opponent has 2 or less Characters, trash 1 card from your hand
Likewise, I really loved the flavor of cards like Vortex Elemental and Dulcet Sirens, but their power level was unfortunately a little low for the tables I wanted to play Cosima at
