the soul stone mtg card COSMIC FOIL from Marvel's Spider-Man Magic the Gathering Proxy Man Art Series Rarity The Soul Stone Art Card

I get it, a tutor a day keeps your opponents at bay, and the stax effects can stack up pretty quickly with an unimpeded Zur attacking each turn

Shes better than a lot of legendary creatures with a higher price tag, like Gwendlyn di Corci, and she fits perfectly into a control deck either as an adjunct or the Commander

Again, the mechanical conceits of discarding as a cost and of tapping numerous creatures are naturally exploitable in Zombie decks

*Shakes Magic 8-Ball* My sources say no

All in all, this card is a total powerhouse and is more than powerful enough for four mana

Just use your first Shining Angel to bait some sort of removal (like Nobleman of Crossout or Sakuretsu Armor), and then play the next one
