It says that whenever you attack with one or more knights, if Sidar Jabari of Zhalfir is in the command zone or on the battlefield, draw a card, then discard a card
These are the white cards you should bring to the table if you have a mono-white deck, but want to be able to play some costly, mana-intensive spells
Even though much of the card is covered in all black, Mew itself is outlined in shades of pink and yellow, with more black in the negative space to give Mew some shading
Just like the DnD deck it's based on, the card can have a range of effects, some game-winning, other catastrophic
It was pretty long, so I just focused on the parts related to setup and basic turn mechanics
Sabrina can still be useful if Grapploct isnt in the Active Spot, however, so bear this in mind
