Sometimes it's a four-mana 1/1 creature
For 5 mana, you can make all your permanents indestructible until end of turn, and you can even activate this ability from the graveyard by exiling it
That means you lose that creature the turn you put this Aura onto the battlefield, and then lose it for the next four turns as well (three turns to remove the counters, and one to sacrifice the Cocoon the creature is still tapped that turn)
Luckily for you, Ive studied and analyzed all eight hundred and sixty one legal white-plus commanders printed at the time of writing so I could present my findings to you as a public service
Cards like Magus of the Candelabra work perfectly with Redshift since you can sink Redshifts mana into Magus ability and gain extra mana to cast on all your potent spells
They remain the same regardless of the value of the card, and include insurance and no hidden charges
