mtg invocation cards Sunbird's (BLC) #116 Originally released April 2017. Starfall Invocation

As long as you have Gale on the battlefield and cast an instant or sorcery, you can then cast whichever nonpermanent card type you didn't already cast from your graveyard

This one is even a creature so you can just destroy it when youre done with the effect

If an infect creature would deal damage to a creature, they instead place -1/-1 counters on that creature equal to their power

This ability doesnt require a tap, either, which means it can serve as an easy infinite mana outlet for many decks

Its useful, and the fact that you can cast them for free and then basically get to draw four more cards, if youve built the deck right, is excellent
