Three mana is a tad expensive for a blink, but these each also draw a card
While this is already a staggeringly high number, thats not even counting the 1000+ multicolored cards as well
It adds 2 damage to every red source you control, making little pings brutal
It brings everyone's artifacts back from the grave, which hopefully benefits the Science deck the most (hopefully you weren't just Bojuka Bogged!)
Put the rest on the bottom of your library in a random order. Thats a lot of text, but basically: if you play a card that costs seven mana, you get to look at the top seven cards of your deck, and then cast a spell from among those cards that costs seven mana or less for free
