If you do, conjure a duplicate of a random creature card with mana value X onto the battlefield, where X is 2 plus the exiled creature's mana value
And unlike Blood Artist and such, these triggers can be directed at a number of places, such as planeswalkers, creatures, or at someone's face
Other options are bounce effects like Crystal Shard or Run Away Together, then spending seven mana to cast Ezuri and pay the three extra to proliferate twice
Use card sleeves for protection, and keep high-value cards in toploaders or magnetic holders to prevent damage.
And there's always some dumpy answer, like the Overlord tutoring up the indestructible Sliver Hivelord to drop, or the Crystalline Sliver and such
When you play this spell, you can show a reply to your post and put the named card into your hand as long as you own it
